No other prophetic saying is as essential to Sufism. It contains, in a few lines, the founding tripartition that situates the spiritual path at the heart of Islam — not beside it, not above it, but as its accomplishment.
The account
The hadith is reported by ʿUmar ibn al-Khaṭṭāb, the second caliph after the Prophet. He bears witness to it in these terms:
One day, as we were sitting with the Messenger of Allāh — upon him blessing and peace — there appeared before us a man with garments of a dazzling whiteness and hair of a deep black, on whom no trace of travel could be seen, and whom none of us knew. He sat down facing the Prophet, set his knees against his, placed his hands upon his thighs and said: “O Muḥammad, inform me of islām.”
The Messenger of Allāh replied: “Islām is that you bear witness that there is no deity but Allāh and that Muḥammad is His Messenger; that you perform the prayer; that you give the prescribed alms; that you fast the month of Ramadan; and that you make the pilgrimage to the House, if you have the means.”
The man said: “You have spoken truly.” — And we were astonished that he should question him and then attest to the truth of the answer.
He then said: “Inform me of īmān.” — “It is that you believe in Allāh, in His angels, in His books, in His messengers, in the Last Day, and that you believe in destiny, in its good as in its ill.” — “You have spoken truly.”
He then said: “Inform me of iḥsān.” — “It is that you worship Allāh as if you saw Him. For if you do not see Him, He, in truth, sees you.”
Then the man asked questions about the end of time, and went away. The Prophet asked me: “O ʿUmar, do you know who that man was?” I replied: “Allāh and His Messenger know better than I.” He said: “That was Gabriel — he came to teach you your religion.” Reported by Muslim and Bukhārī
The text is so named because it is the archangel Jibrīl · جِبْرِيل (Gabriel) who questions the Prophet under the appearance of a man. The pedagogical method is clear: Gabriel already knows, but he questions before the Companions so that the Prophet may teach them. The whole of religion is unveiled in three key words.
The three degrees — a vertical architecture
Islam — that is, the path revealed by the Quran and the Prophet — unfolds along three superimposed levels, from the most outward to the most inward. Each level enwraps the preceding one and accomplishes it.
1 · Islām · الإِسْلَام — active submission
The first degree is that of outward practice. The word islām, derived from the root S-L-M which means both peace and submission, here designates the act of submitting actively to the divine will, and of translating it into deeds: the five Pillars.
- The profession of faith — shahāda · شَهَادَة.
- The ritual prayer — ṣalāt · صَلَاة, five times a day.
- The prescribed alms — zakāt · زَكَاة.
- The fast of the month of Ramadan — ṣawm · صَوْم.
- The pilgrimage to Mecca — ḥajj · حَجّ.
This is the level of the sharīʿa · شَرِيعَة — the religious Law. It is visible, it can be taught, it can be codified. It disciplines the body and structures the community. It is essential — but it does not suffice.
The Bedouins said: “We believe.” Say: “You do not believe — say rather: we submit. For faith has not yet entered your hearts.” Quran 49:14
2 · Īmān · الإِيمَان — the faith of the heart
The second degree is inward. Īmān is not seen, not measured, not legislated. It has its seat in the heart, the place where the invisible is recognised. To believe in God, in His angels, in His books, in His messengers, in the Last Day, in destiny — this is not only to know intellectually that these realities exist, it is to have the living certainty of them, which orients one's existence.
One can perform the rites perfectly without having faith (as verse 49:14 indicates). One can also have faith without being able, for a time, to perform the rites. But these two levels are normally bound together: practice nourishes faith, and faith vivifies practice.
Īmān is governed by theology — the ʿaqīda · عَقِيدَة, dogmatics. But Sufism reproaches the scholastic theologians for turning faith into a system of propositions to be defended. For the Sufis, faith is not a correct opinion, it is a presence of the heart.
3 · Iḥsān · الإِحْسَان — excellence, the “beautiful”
It is here that the hadith reaches its summit. Iḥsān comes from the root Ḥ-S-N which says at once beauty, goodness, perfection. Mūḥsin, the active participle, designates the one who does things beautifully-well, who acts with excellence — including towards animals and plants.
In the hadith, the Prophet defines iḥsān by a short and overwhelming formula: “That you worship Allāh as if you saw Him. For if you do not see Him, He, in truth, sees you.”
Everything lies in the “as if”. It is not the presumed certainty of seeing God — that would be presumption. It is the quality of presence that would consist in conducting oneself as if the divine Presence were immediately perceptible. Which changes everything. The ritual gesture becomes an encounter. Speech becomes a conversation. The gaze upon another becomes a gaze upon a theophany. The least act of the day is charged with an unusual intensity.
Iḥsān adds neither a belief to faith nor a rite to practice: it transforms them from within, making of each act a presence. Classical formulation of Sufism
Sufism as the science of iḥsān
It is precisely with this third degree that the Sufis, from their very beginnings, identified their path. Sufism — at-taṣawwuf · التَّصَوُّف — is the science of iḥsān. Its aim is not to replace the sharīʿa or theology, but to inhabit both with this quality of presence.
One can then understand why the great classical Sufis in no way opposed the scholars of the Law or the theologians. They were themselves, most often, accomplished jurists and theologians. But to the knowledge of rules and beliefs they added the inner science of the Presence — the maʿrifa · مَعْرِفَة, direct knowledge.
The Sufis compare Islam to an almond: the shell is the sharīʿa, the almond itself is the īmān, and the precious oil drawn from it is the iḥsān. Without the shell, the almond rots. Without the almond, the shell is empty. But without the oil, the almond remains mute: it does not give its light.
An integral coherence
The hadith of Gabriel thus saves Sufism from two possible drifts:
- It roots it in common practice — the islām of all, the five Pillars, the praying community. There is no Sufism outside Islam: one cannot attain excellence without first having faith, nor cultivate faith without translating it into deeds.
- It distinguishes Sufism from mere legalism — dry practice, frozen belief. The path is living, transforming, dynamic. It aims at a state of being, not at a conformity.
This is why, to the question “What is Sufism?”, several great masters have answered simply: “Sufism is iḥsān.” Nothing more, nothing less. It is Islam full and integral — Islam lived in all its depth.
Worship Allāh as if you saw Him. For if you do not see Him, He, in truth, sees you. The Prophet Muḥammad, the hadith of Gabriel
