The vocabulary of the Qur'an, defined from its roots.

Literally: To make one; to declare something single and unmatched.

Singling out Allah alone in His lordship, His names and attributes, and in all worship. It is the message of every prophet and the condition on which every deed is accepted.

Literally: One who owns, nurtures a thing to completion, and has authority over it.

The Lord who creates, sustains, raises step by step and commands. The word carries ownership and upbringing together, which is why the Qur'an uses it when speaking of Allah's care in someone's personal history.

Literally: Ownership joined with the power to dispose of what is owned.

Absolute dominion — the right and the ability to command creation. Everything a person 'owns' exists inside a dominion belonging to Allah alone.

Literally: To make something pure, free of anything mixed into it.

Purifying an act of worship so it is for Allah alone, with no share in it for reputation, praise or habit. Without it a deed can be outwardly perfect and inwardly void.

Literally: To do something beautifully, to excel at it.

Excellence in worship and dealing with people: to worship Allah as though you see Him, knowing that if you do not see Him, He sees you. It is quality of deed, which is exactly what Sūrat al-Mulk says the test measures.

Literally: To place a shield between yourself and something harmful.

God-consciousness that acts as a barrier: doing what He commanded and leaving what He forbade, out of awareness that He sees you — especially in private.

Literally: To acknowledge a favour and show its effect.

Gratitude that appears in three places: the heart's recognition, the tongue's mention, and the limbs' obedience. Speaking about a blessing is part of thanking for it, not boasting.

Literally: To confine or restrain something in one place.

Holding the self steady: on obedience, away from disobedience, and under decree. In al-Kahf it is also the condition of learning — patience with a teacher and with what you cannot yet see the reason for.

Literally: Putting gold in fire to separate the pure metal from the dross.

A trial that reveals what a person really is. Al-Kahf is organised around four of them — faith, wealth, knowledge and power — and the Prophet ﷺ tied its opening āyāt to protection from the greatest fitnah, the Dajjāl.

Literally: The causes of revelation.

The events, questions or incidents during which a verse or passage was revealed, established through authentic narration. Knowing them anchors a verse in a real situation and blocks misreading; scholars insisted they be reported, never guessed.

Literally: To uncover and make plain.

Explanation of the Qur'an's meaning. The soundest order is: Qur'an explained by Qur'an, then by the Sunnah, then by the Companions, then by the Successors — and only then by language and considered opinion.

Literally: To return something to its origin or outcome.

In the Salaf's usage, the real outcome or reality a text refers to; in later usage, interpreting a word away from its apparent meaning for a reason. Al-Khiḍr's disclosure of the reasons behind his three acts is called taʾwīl in the Qur'an itself.

Literally: Makkan and Madinan.

The standard classification by time: whatever was revealed before the Hijrah is Makkī, whatever came after it is Madanī — even if revealed in Makkah, as at the conquest. Makkī passages typically build belief, the Hereafter and character; Madanī passages typically legislate for a community.

Literally: Firmly decided, and resembling / ambiguous.

Verses of clear, decisive meaning are the foundation of the Book; verses whose full meaning is not decisively clear are referred back to them. Chasing the ambiguous while ignoring the clear is named in the Qur'an as a sign of a deviated heart.

Literally: The one that supersedes, and the one superseded.

A later ruling replacing an earlier one within revelation itself. It applies to rulings, not to reports about Allah, and it is one reason revelation order matters when studying.

Literally: A sign, a mark that points to something beyond itself.

A verse of the Qur'an — and also any sign in creation. The Qur'an uses one word for both, because a verse and a sunrise are doing the same work: pointing to the One who made them.

Literally: An elevated wall or enclosure — a bounded, raised structure.

A chapter of the Qur'an with a defined beginning and end. The name fits the study method: each surah is a walled unit with its own architecture, argument and conclusion.

Literally: To look at the dubur — the far end, the outcome — of a thing.

Reflecting on the Qur'an by following a passage through to what it demands of you. It is the stated purpose of the revelation, and the reason reading without understanding leaves a person unchanged.

Literally: To mention, and to remember — the tongue and the heart in one word.

Remembrance of Allah by heart and tongue, including recitation of the Qur'an, which is itself called adh-Dhikr. Al-Kahf commands it as the repair for forgetting.

Literally: Anything given to a creature from which it benefits.

Provision — not only wealth, but health, knowledge, family and time. Sūrat al-Mulk pairs it with a command to work: walk the earth's shoulders, then eat of His provision.

Literally: The remaining righteous things.

The deeds that outlast this world's ornament. The Salaf explained them as subḥān Allāh, al-ḥamdu lillāh, lā ilāha illā Allāh and Allāhu akbar — and more broadly every act of obedience whose reward endures.

Literally: The nearer one — feminine of adnā, 'closer' and also 'lower'.

This present life, named for being near at hand and lower in worth than what follows. The Qur'an does not condemn it; it ranks it.

Literally: The last one, what comes after.

The everlasting life after death, including the resurrection, the reckoning, and the final abodes. The Makkan surahs argue for it constantly because everything else in the religion follows from it being real.

Literally: To spread out — as a rolled cloth is unfurled.

The resurrection, when the dead are raised and spread forth for judgement. Al-Mulk attaches it to the most ordinary activity there is: earning your living.

Literally: What is absent from perception.

What is hidden from creation: Allah Himself, the angels, the decree, the Hereafter — and also your own private state. Belief in the unseen is the first quality the Qur'an names for the God-conscious.

Literally: Something singular and unmatched; a child who has lost a father before puberty.

An orphan. The same root gives durrah yatīmah — a unique pearl — which is why the word carries both vulnerability and worth. Care for the orphan is repeatedly placed beside belief itself.

Literally: To leave, abandon, cut off from.

The migration from Makkah to Madinah in 1 AH, the dividing line between Makkī and Madanī revelation — and, in the Prophet's ﷺ words, also the abandoning of what Allah forbade.

Literally: A slackening, an interval of stillness.

The pause in revelation after the first verses in Ḥirāʾ, during which the Prophet ﷺ grieved and the Quraysh mocked. It ended with Sūrat aḍ-Ḍuḥā — the reason that surah reads as consolation.

Literally: A way of travelling; hence a person's course of life.

The biography of the Prophet ﷺ — his conduct, campaigns and character, drawn from hadith and the classical maghāzī works. Studied alongside revelation, it turns the Qur'an from a text into a record of a life.

Literally: To return to something repeatedly.

The classical discipline of scheduled revision of what you have memorised or studied. The Prophet ﷺ warned that the Qur'an slips away faster than tethered camels without it — the same principle modern research calls spaced repetition.
