Al-Qalb — Rawzat

The Heart in the Quran — More than Emotion

English-speaking readers sometimes assume “heart” in the Quran is a metaphor for emotion — the way Western culture uses “heart” to mean feelings. The Quranic qalb is far more comprehensive: it is the faculty of understanding, the capacity for faith, the organ of spiritual sight, and the place where divine guidance is either received or rejected.

“Indeed, in that is a reminder for whoever has a heart or who listens while he is present [in mind].” (50:37) — “having a heart” means being capable of spiritual attentiveness.

“So have they not traveled through the earth and have hearts by which to reason and ears by which to hear? For indeed, it is not eyes that are blinded, but blinded are the hearts which are within the chests.” (22:46) — Spiritual blindness is blindness of the heart, not the eyes. The physical organ of sight functions, but the inner faculty of spiritual perception is closed.

“And He brought down tranquility (sakina) upon them and rewarded them with a near conquest.” (48:18) — The sakina descends specifically into the heart.

The heart in the Quran is:

The seat of ‘aql (reason/understanding)
The seat of iman (faith): “He has written iman in their hearts” (58:22)
The seat of dhikr (remembrance): “Truly in the dhikr of Allah do hearts find rest.” (13:28)
The seat of taqwa: “That indeed is from the taqwa of the hearts.” (22:32)
The seat of nifaq (hypocrisy): the Quran describes the hypocrites’ hearts as “diseased” (2:10)

The States of the Heart

The Quran describes the heart in multiple states — some open, some closed:

The Living Heart — Al-Qalb al-Salim

“The day when neither wealth nor sons will avail, except for one who comes to Allah with a sound heart (qalb salim).” (26:88-89) — The ultimate goal: to meet Allah with the qalb salim, the heart that is whole, sound, and free from the diseases of attachment, pride, and heedlessness. Ibrahim (AS) specifically is described as having this quality.

The Fearful and Returning Heart — Al-Qalb al-Munib

“Who feared the Most Merciful unseen and came with a returning heart.” (50:33) — The heart that, even without direct vision of the divine, maintains conscious relationship through fear and return (inaba).

The Tranquil Heart — Al-Nafs al-Mutma’inna / Qalb Mutma’in

“Truly in the dhikr of Allah do hearts find rest (tatma’inn).” (13:28) — The heart that has found its rest in divine remembrance. This verse is one of the most beloved in the Quran precisely because it names the experience that dhikr produces: the quieting of the anxious heart, the settling of the restless soul.

“O soul at peace, return to your Lord, satisfied and pleasing [to Him].” (89:27-28) — The Quran’s address to the mutma’inn soul: called back to its divine source.

The Sealed Heart — Qalb Makhtum

“Allah has sealed their hearts and their hearing, and over their vision is a veil.” (2:7) — The most feared state: a heart sealed against divine guidance. The Quran describes this as the consequence of repeated rejection — each time divine guidance is rejected, the heart hardens a layer further, until the sealing becomes complete.

“Is the one whose chest Allah has opened to Islam and he is upon a light from his Lord [like the one whose heart is hard]? So woe to those whose hearts are hardened against the remembrance of Allah.” (39:22) — The opened chest (sharh al-sadr) as the opposite of the hardened heart.

The Diseased Heart — Qalb Marid

“In their hearts is disease (marad), so Allah has increased their disease.” (2:10) — The disease of nifaq (hypocrisy), of spiritual duplicity. The heart that presents one face to the community while holding another in private is a diseased heart.

The Heart and Dhikr

The Quranic prescription for the heart’s health is dhikr — the remembrance of Allah:

“Truly in the dhikr of Allah do hearts find rest.” (13:28)

This verse is the central statement of Islamic psycho-spiritual health: the heart’s rest is found not in achievement, accumulation, relationships, or knowledge — but in the remembrance of the divine. The heart is constitutionally oriented toward the divine (this is the fitra) and only in the divine does it find the rest that its constitution demands.

“Remember your Lord within yourself with humility and in awe, without announcing it openly, morning and evening — and do not be among those who are heedless.” (7:205) — Private, inner dhikr as the daily maintenance of the heart’s health.

The Prophet (SAW) said: “Everything has a polish that removes rust from it, and the polish for the hearts is the dhikr of Allah.” — Dhikr as the practical technology for maintaining the heart’s capacity for divine reception.

The Heart and the Quran

The Quran itself is described as a healing for the hearts:

“O mankind, there has come to you a guidance from your Lord, and a healing for what is in the breasts (shifa’ li-ma fi’l-sudur), and guidance and mercy for the believers.” (10:57)

“We send down of the Quran that which is healing and mercy for the believers.” (17:82)

The Quran heals the heart because the heart’s disease is disconnection from the divine — and the Quran is the direct communication from the divine. Reading the Quran, reflecting on it (tadabbur), allowing its verses to land in the heart rather than passing through the mind only — this is the primary medicine for the heart’s diseases.

“Do they not then reflect on the Quran? Are there locks upon their hearts?” (47:24) — The Quran asks why hearts don’t open to it: the locks are ego, pride, hardness, and heedlessness — all conditions of the heart.

The Heart in the Ismaili Teaching

The Ismaili-Tayyibi tradition places the qalb at the center of its spiritual psychology:

The Heart as Faculty of Ta’wil

The batin of the Quran is not received by the analytical mind — it is received by the qalb. The ta’wil speaks to the heart because the heart is the inner faculty that can receive inner meaning. A person can read a ta’wil with the mind and find it interesting; a person who receives it with the qalb experiences it as recognition — the fitra responding to truth it already knew.

The Heart and Walayah

The walayah of the Imam — the covenant and relationship with the living Imam — is not a contract but a heart-relationship. The formal taking of misaq (the covenant) is the outward expression; the inward reality is the heart’s orientation toward the Imam as the source of divine guidance. A mumin who has taken the misaq without the heart’s orientation has the form without the soul.

Conversely, the heart that is genuinely oriented toward the Imam has walayah even when circumstances complicate formal expression. The Quran’s comment on the believer: “He has written iman in their hearts.” (58:22) — Iman is in the heart before it is in the performance.

The Opened Heart — Sharh al-Sadr

“Has He not expanded for you your chest (sharh al-sadr)?” (94:1) — The verse addressed to the Prophet. The sharh al-sadr (opening/expansion of the chest) is the specific spiritual experience associated with the reception of divine guidance: the feeling of the heart opening, of space expanding inside, of constraint falling away.

The Quran mentions this experience for the Prophet himself (94:1), for Ibrahim (26:13 — when he prays for it before speaking to his people), and as the mark of someone whom Allah has guided to Islam (39:22). It is the experiential confirmation of the heart’s receptivity to divine guidance.

In the Ismaili teaching, the sharh al-sadr is the characteristic experience of receiving the Imam’s ta’wil. The ‘ilm that enters through the Imam’s walayah does not merely inform — it expands. This expansion of inner space is the heart’s response to truth.

The Heart and Prayer

The salah (prayer) is understood in Islamic teaching as the primary practice for the heart’s orientation:

“Establish prayer for My remembrance.” (20:14) — Prayer as dhikr, as heart-practice.

The Quran identifies the failure of prayer that hasn’t reached the heart: “So woe to those who pray but are heedless of their prayer.” (107:4-5) — The outward form of prayer without the heart’s presence is prayer that misses its purpose.

The heart’s presence in prayer — khushu’ (humility, focused presence) — is what makes salah the medicine it is intended to be. The Quran: “Recite what has been revealed to you of the Book and establish prayer. Indeed, prayer prohibits immorality and wrongdoing, and the remembrance of Allah is greater.” (29:45) — The prohibiting of immorality comes from the prayer as dhikr-practice for the heart; a heart regularly oriented toward the divine in khushu’ is a heart being continuously recalibrated.

Ta’wil of the Heart

The zahir of the qalb is the organ in the chest — the beating center of physical life, the seat of emotion in the common understanding.

The batin of the qalb is the center of the human being’s spiritual existence — the faculty by which the divine is known, the capacity for iman, the organ of recognition that responds to truth with the sakina (tranquility) that the Quran describes. The heart is the faculty that knows from within rather than deducing from without — it is the organ of direct knowing, not inferential knowing.

The entire spiritual life is the cultivation of this faculty: keeping it alive through dhikr, healing it with the Quran, opening it through walayah, and finally arriving at the state the Quran calls qalb salim — the sound, whole, healthy heart that meets Allah with nothing between itself and the divine.

“Beware! Truly in the body there is a lump of flesh — if it is sound, the whole body is sound; and if it is corrupt, the whole body is corrupt. Truly it is the heart.” — The Prophet (SAW) (Bukhari and Muslim)
