Diseases of the Heart: The Inner Conditions That Require Treatment
The classical analysis of what can go wrong in the heart. The specific spiritual diseases identified by al-Ghazali and Ibn al-Qayyim, and how they are treated.
The Heart As Subject of Diseases
The Quran speaks repeatedly of the heart's conditions. Some hearts are salim (sound); others have marad (disease); others are qasi (hardened); others are maktum (sealed). The heart, in the Quranic vision, is not just an organ of feeling but the seat of moral and spiritual life — and like any seat of life, it can flourish or sicken.
The verse refers to the hypocrites, but the diagnostic framework — that hearts can have disease — is general. The Quran applies it broadly to those whose inner condition has gone wrong.
The verse identifies a specific kind of disease — the heart's blindness — that prevents the recognition of what the eyes themselves see plainly. The disease operates at the level of inner perception rather than outer sensation.
The classical scholars, building on these Quranic foundations, developed detailed analyses of specific spiritual diseases. The most comprehensive treatments are found in al-Ghazali's Ihya (particularly the third quarter, Rub' al-Muhlikat — "the Quarter of Destroyers") and in Ibn al-Qayyim's Madarij al-Salikin and al-Da' wa al-Dawa.
This day's reading examines the major diseases identified by these classical authorities, how they manifest, and how they are treated.
Riya: Spiritual Showing-Off
The first disease, and one the Prophet ﷺ described as the most subtle threat to the believer, is riya — performing acts of religion for the purpose of being seen by people. The Prophet ﷺ said: "What I fear most for you is the lesser shirk." The companions asked: "What is the lesser shirk, O Messenger of Allah?" He said: "Riya. Allah will say on the Day of Judgement, when He is rewarding people for their deeds: 'Go to those for whom you were showing off in the world and see whether you find any reward with them.'"
The hadith is theologically severe. Riya is identified as a form of shirk — associating something other than Allah with Him in the act of worship. When the worship is performed partly for the recognition of people, the people have become a kind of partner in what should have been offered exclusively to Allah. The intention has been split between Allah and the audience.
Manifestations include:
- Performing prayer with greater concentration when others are watching - Increasing recitation, charity, or other acts when one knows they will be observed - Mentioning one's good deeds in conversation in ways that elicit recognition - Choosing specific religious practices because they will be visible rather than for their inherent value - Adopting religious appearance (dress, beard, expression) primarily to be seen as religious rather than as authentic expression
The treatment, classical scholars have outlined, involves several elements:
Awareness of Allah's sight as primary. The believer who has internalised that Allah sees the inner state and rewards based on it (rather than based on what people see) has the foundational orientation that opposes riya. The cultivation of this awareness — through dhikr, reflection, and the practices of ihsan — gradually displaces the orientation toward human audiences.
Privacy in voluntary worship. The Prophet ﷺ recommended that voluntary prayer (nawafil) be performed at home where possible, and that voluntary fasts not be announced. The privacy of voluntary acts removes the audience that riya requires. Some classical scholars have specifically recommended performing some voluntary acts in private specifically as a treatment for riya.
Continuing the act despite the awareness of being seen. A subtle issue arises: if the believer abandons a worship act because they realise it might appear ostentatious, they have given riya a different kind of victory. The classical recommendation is to continue the worship while working on the inner state — not to abandon the worship out of fear of riya, but to perform it with renewed attention to who it is actually being offered to.
Recognition that complete elimination is unlikely. Some classical scholars have observed that riya in its most subtle forms cannot be entirely eliminated by ordinary believers; only the prophets and the most advanced of the awliya fully escape it. The realistic goal is to minimise it, to recognise it when it arises, and to renew sincerity (ikhlas) repeatedly. The believer who is working on this even imperfectly is doing better than the believer who has not noticed the issue.
Ujb: Self-Admiration
Closely related to riya but distinct from it is ujb — admiring oneself, taking pride in one's own religious achievements. Where riya is performing for others' recognition, ujb is the inner state of being impressed with oneself.
The Prophet ﷺ said in a hadith preserved by al-Bayhaqi: "Three things destroy: stinginess that is obeyed, desires that are followed, and a person being amazed by themselves." The hadith places ujb among the most serious destroyers. The believer who is impressed with their own piety, learning, charity, or any other quality has, in subtle form, attributed to themselves what was actually a gift of Allah.
The classical analysis identifies several specific manifestations:
- Inwardly comparing oneself favourably to less religious people - Taking quiet satisfaction in one's prayer, fasting, or charity as one's own achievement - Treating one's spiritual progress as evidence of one's worth rather than Allah's grace - Becoming dismissive or condescending toward those who appear to be at lower spiritual stages - Attributing one's success in religion to one's own effort rather than to divine assistance
The treatment includes:
Recognition that all good is from Allah. The Quran says: "Whatever good comes to you is from Allah, and whatever evil befalls you is from yourself" (4:79). The believer's good deeds are themselves gifts — Allah enabled them, granted the time, gave the awareness, accepted the action. None of this is the believer's own achievement in the sense that ujb implies.
Awareness of one's continuing failures. The believer who is truly honest with themselves about their continuing failures has less room for ujb. The honest muhasabah we examined yesterday treats the disease at this point — the believer who sees the failures clearly cannot easily be impressed with themselves.
Reflection on the achievements of those greater. The believer who reflects on the taqwa of the prophets and companions sees their own piety in proper perspective. Compared to Abu Bakr's taqwa, compared to the Prophet's ﷺ devotion, our own efforts shrink to nearly nothing. The reflection prevents inflation.
Recognition that the end has not yet come. The believer's spiritual state at any given moment is provisional. The end of life has not arrived; the final accounting has not been rendered. Allah may take spiritual gifts back if they produce ujb. The classical scholars have warned against considering oneself secure: the believer who feels secure in their piety has, by that very feeling, slipped.
Hasad: Envy
Envy — hasad — is a disease that the Prophet ﷺ identified explicitly. He said: "Beware of envy, for envy consumes good deeds as fire consumes wood."
The classical definition of hasad is wishing that the blessings someone else has would be removed from them. It is distinguished from ghibtah (a related but different state) which is wishing that one had similar blessings without wishing the other person to lose theirs. Ghibtah is permitted in religious matters; hasad is forbidden in all matters.
Hasad is classically identified as the first sin committed in the universe — Iblis's envy of Adam's status, which led to his refusal to bow and his fall from grace. The Quran's account of this in 7:11–18 and elsewhere shows envy as the engine of Iblis's rebellion. The diagnosis has implications: envy is not just a minor flaw; it is the mechanism by which Iblis became Iblis, and the believer who indulges envy is following the same trajectory.
Manifestations include:
- Inward distress when hearing of others' success - Quiet pleasure when hearing of others' difficulties - Repeating reports about others that emphasise their failings - Withholding due praise of others to avoid acknowledging their merits - Active efforts to undermine those whose blessings one envies
The treatment includes:
Recognition that Allah's distribution of blessings is wise. The believer who has internalised that Allah distributes blessings according to His wisdom (and according to factors known only to Him) cannot reasonably envy what He has given to others. To envy is to question the wisdom of the distribution.
Genuine prayer for others' continued blessing. The Prophet ﷺ recommended praying for others when seeing their blessings — saying barak Allahu lak (may Allah bless it for you) and similar phrases. The active prayer counters the inner pull toward envy. The repeated practice of such prayers, performed sincerely, gradually reorients the heart.
Engagement with the Quranic verses on envy. Sura al-Falaq (113), one of the two final suras of the Quran, includes in its protection-seeking the protection from "the envier when he envies" (113:5). The recitation of the sura, particularly the morning and evening adhkar, includes this protection. The believer who recites it is reminded of the seriousness of envy and seeks protection from both being envied and being an envier.
Active work on contentment. The believer who has cultivated qana'ah (contentment with what Allah has given) has the foundation that opposes envy. Qana'ah and envy are mutually exclusive; cultivating one displaces the other.
Kibr: Pride
Pride — kibr — is identified by the Prophet ﷺ as a disease that excludes the proud from Paradise. He said: "No one will enter Paradise who has an atom's weight of pride in his heart." The companions, alarmed, asked: "What if a man likes his clothes and shoes to look good?" The Prophet ﷺ said: "Allah is beautiful and loves beauty. Pride is rejecting the truth and looking down on people."
The hadith provides the classical definition. Pride has two components: rejecting truth (refusing to accept truth from those one considers beneath oneself) and looking down on people (treating others as one's inferiors). Both must be present for the full disease. The believer who appreciates good clothing, who maintains pleasant appearance, who has self-respect — these are not kibr unless they involve the rejection of truth or the contempt of others.
The classical analysis distinguishes:
Pride toward Allah — refusing to submit to His commands, considering oneself above the requirements of religion. This is the most severe form, identified with the disease of Iblis himself.
Pride toward people — looking down on others, considering oneself superior to them. This may be based on wealth, lineage, learning, beauty, or any other ostensible advantage. The classical scholars have noted that the bases vary but the underlying disposition is similar — the believer treating themselves as better than other servants of Allah.
Pride about truth — refusing to accept correction or new understanding because of who is offering it. The believer who would accept the same correction from a different source but refuses it from this source has shown pride.
The treatment includes:
Reflection on origins and end. The Prophet ﷺ said: "Adam was created from dust." The reflection on one's origin (a clot of blood, a fertilised cell) and end (a corpse) is a classical antidote to pride. Whatever one's current achievements or appearance, the bracketing facts of origin and destination make the current intermediate state look less impressive.
Service to those society treats as inferiors. The Prophet ﷺ would mend his own clothes, sweep his own home, milk his own goat. He would sit with the poor, eat with servants, accept invitations from the simplest people. The active engagement with what culture treats as beneath one's dignity is a treatment for kibr. The believer who serves others — particularly those society would consider lower — reshapes their own disposition through the practice.
Recognition of one's own failures. Pride is sustained by selective awareness — focusing on what one has achieved while ignoring what one has failed at. Honest muhasabah introduces awareness of failures that pride cannot easily survive.
Hubb al-Dunya: Love of the World
The most pervasive of the spiritual diseases, perhaps, is hubb al-dunya — love of the world, attachment to the temporary in preference to the permanent. The Prophet ﷺ said: "Love of the world is the root of every error."
The classical analysis is precise. The dunya (the world) refers not to physical objects or natural blessings but to the orientation of seeking the world as the ultimate goal. The believer who lives in the world, eats from the world, works in the world, has children and homes — none of this is hubb al-dunya. Hubb al-dunya is the orientation that has placed worldly success, comfort, recognition, or accumulation as the actual goals of one's life, displacing the orientation toward Allah and the next world.
Manifestations include:
- Feeling fulfilled by worldly success in a way that ultimate fulfilment should not be sought from - Distress at worldly loss in a way that suggests the world was the primary investment - Spending the dominant share of one's time, attention, and energy on worldly pursuits - Treating religion as one compartment among many rather than as the orienting framework - Sacrificing religious commitments for worldly opportunities
The treatment requires sustained engagement with the doctrines of the next life and active disciplines of detachment:
Regular reflection on death and what follows. The Prophet ﷺ said: "Frequently remember the destroyer of pleasures." The destroyer of pleasures is death. Regular reflection on it — visiting graveyards, attending funerals, reading about the death and what follows — punctures the illusion that the world is the primary reality.
Living below one's means in some respects. The Prophet ﷺ lived simply even though, as the leader of an expanding community, he had access to greater wealth. The discipline of voluntary simplicity — choosing simpler food, simpler clothing, simpler accommodation in some respects — keeps the heart from becoming too attached to material elaboration.
Charity that is felt. Giving charity that one notices — that affects one's resources, that requires some sacrifice — is a practical detachment from the world. Token charity that costs nothing produces little spiritual effect; charity that one feels reshapes one's relationship with possessions.
Use of the world as means, not end. The believer who has zuhd (proper detachment) does not necessarily live in poverty. They live with whatever Allah has given them, but use it as means rather than treating it as end. The wealth, the home, the family, the position — all are means by which Allah is to be served and the next life prepared for.
What This Teaches
Several lessons emerge.
The Diseases Are Diagnosable
The classical analysis provides diagnostic categories that allow the believer to identify what specifically is going on inside them. Without categories, the inner life is opaque; with categories, specific patterns can be recognised. The believer who notices that they are feeling hasad — and who has the category for what that is — can begin specific work on it. The believer without categories has only vague sense that something is wrong.
Diseases Are Treatable
The classical methodology assumes that the diseases are not fixed conditions. They are treatable. The treatment requires sustained work, but progress is possible. The believer who is currently struggling with pride is not condemned to permanent pride; the believer who notices envy can work on it; the believer who recognises love of the world can shift their orientation.
The Treatments Are Practical
The classical treatments are not abstract. They are specific practices that can be implemented immediately. Praying for the person one envies, serving those one feels superior to, simplifying one's lifestyle, reflecting on death — all are concrete actions that the believer can undertake today. The methodology is operational.
The Work Is Ongoing
None of the diseases is treated by a single intervention. They require sustained engagement across years. The believer who treats kibr this week may find it returning in subtle form next month. The work is not one-time; it is a continuing dimension of the religious life. This is not discouraging; it is realistic. The diseases are deep-rooted; treating them takes time.
Other Diseases the Classical Tradition Identifies
The five diseases above are among the most prominent, but the classical tradition identifies many others. Several deserve at least brief mention.
Ghadab (Anger). The Prophet ﷺ said when a man asked him for advice: "Do not get angry." He repeated this several times to emphasise it. Anger, when uncontrolled, is identified as a disease that produces specific harms: damaged relationships, broken oaths, words that cannot be retrieved, actions taken in passion that are regretted in calm. The treatment includes specific prophetic instructions — saying a'udhu billahi min ash-shaytan ir-rajim (I seek refuge in Allah from the accursed Satan) when anger arises, sitting down if standing, lying down if sitting, performing ablution to cool the body and the disposition. The classical scholars have noted that the goal is not the elimination of anger entirely (which is unrealistic and would itself be problematic) but the development of forbearance (hilm) that allows anger when it is appropriate while preventing it when it is not.
Ghaflah (Heedlessness). The Quran warns repeatedly against ghaflah — the state of being unaware, distracted, not present to what matters. "And do not be among the heedless" (7:205). The disease of ghaflah is the absence of remembrance — going through one's life without attention to Allah, without awareness of the eventual accounting, without engagement with what is actually significant. The treatment is the cultivation of dhikr — sustained, regular remembrance that keeps awareness alive. The hadith says: "The example of one who remembers his Lord and one who does not remember Him is like the example of the living and the dead." Ghaflah is, in this prophetic image, a kind of spiritual death; dhikr is what restores life.
Bukhl (Stinginess). The Quran identifies stinginess as one of the qualities that destroy: "Truly, man is to his Lord ungrateful, and he is, indeed, a witness to that. And indeed, he is, in love of wealth, intense" (100:6–8). Stinginess is the disposition that holds tightly to wealth even when giving would be appropriate, that calculates every potential expense, that looks for reasons not to spend. The treatment is consistent practice of charity — giving regularly, even when small amounts, until the disposition begins to soften. The believer who has practised generosity for years has developed a different disposition than the believer who has hoarded for years.
Hubb al-Jah (Love of Status/Recognition). A subtle disease that the classical tradition identifies as particularly dangerous to scholars and people of religious responsibility. Hubb al-jah is the love of being known, respected, looked up to. It can corrupt religious activities — the scholar who teaches partly because of the recognition that comes with teaching, the imam who leads partly because of the position that comes with leading, the writer who writes partly because of the audience that comes with writing. The treatment involves performing some activities anonymously, withdrawing from leadership opportunities at times, cultivating awareness that the only recognition that matters is Allah's. Several classical scholars have noted that hubb al-jah may be the last disease to fall away — even as other diseases are healed, the love of recognition can remain.
Tul al-Amal (Long Hopes / Far-Reaching Ambitions in This World). A specific disease identified by Ibn al-Qayyim and others is the tendency to plan far into a future life that one may not see. The believer who plans extensively for distant worldly goals while neglecting the imminent next life has misallocated attention. The treatment is regular awareness of mortality — recognising that the future one is planning for may not arrive, while the next world is certain. This does not mean abandoning planning; it means proportioning planning appropriately to the certainty of the next life and the uncertainty of the worldly future.
Su' al-Zann (Bad Opinion of Others). The Quran instructs: "O you who have believed, avoid much suspicion. Indeed, some suspicion is sin" (49:12). The disease of habitually thinking the worst of others — assuming bad motives, expecting bad outcomes, interpreting actions uncharitably — corrupts relationships and is itself displeasing to Allah. The treatment includes the active cultivation of husn al-zann (good opinion) — choosing to interpret ambiguous situations charitably, giving people the benefit of the doubt, trusting Allah's judgment rather than substituting one's own.
These additional diseases are not exhaustive. The classical literature identifies many more — ghibah (backbiting), namimah (slander), takabbur (arrogance), yas (despair), qunut (depression in the spiritual sense, distinct from the prayer of qunut), qaswah (hardness of heart), and many others. Each has its specific manifestations and its specific treatments. The believer engaging seriously with the classical tradition gains, over time, an extensive vocabulary for diagnosing what specifically is happening inside themselves and a corresponding methodology for addressing it.
A Closing Reflection
The classical analysis of the diseases of the heart is a precious resource. The believer who engages with it — even at a basic level, through reading selections from al-Ghazali or Ibn al-Qayyim — gains diagnostic capacity that ordinary religious teaching does not provide. The five pillars and the six pillars are necessary but not sufficient; the full religious life includes the work of identifying and treating what has gone wrong in the heart.
For modern Muslims, this work has not become less relevant. If anything, the conditions of modern life — pervasive social media that fuels comparison and envy, consumer culture that nurtures love of the world, achievement culture that feeds self-admiration, identity-display culture that encourages spiritual showing-off — have made the diseases more virulent. The classical methodology is needed now as much as ever.
May Allah grant us hearts that are sound, awareness of the diseases when they arise, the practical discipline to treat them, and the patience to sustain the work across years. May He protect us from the diseases that destroy and grant us the virtues that save. Amin.
