wāḥidah (of a soul, word, community) : wāḥid (of God)
«He is God, One»
interpreted· quran by quranThe sūra the tradition calls «a third of the Qurʾān» — oneness stated in four lines 112:1–112:4.
قُلْ هُوَ ٱللَّهُ أَحَدٌ
Say, "He is Allah, [who is] One,
Aḥad — not merely «one» in a series but uniquely one, one-of-a-kind.
ٱللَّهُ ٱلصَّمَدُ
Allah, the Eternal Refuge.
Al-Ṣamad — the one to whom all turn and who needs none; the self-sufficient.
لَمْ يَلِدْ وَلَمْ يُولَدْ
He neither begets nor is born,
Neither begets nor is begotten — oneness excludes both a father and a son; He is uncaused and uncausing of any like Him.
وَلَمْ يَكُن لَّهُۥ كُفُوًا أَحَدٌۢ
Nor is there to Him any equivalent."
And there is none comparable to Him — the seal: no equivalent, no peer, no second.
One word, two directions
interpreted· quran by quranA distinction the form-split makes visible.
The root splits almost evenly: wāḥidah (feminine) 31× and wāḥid (masculine) 30×. The feminine rarely means God — it means one soul from which humanity was made 4:1, one community the people once were 2:213, one word of the messengers. The masculine carries the doctrine: ilāhun wāḥid, «one God» 2:163, 16:51. So the Qurʾān's vocabulary of oneness is not reserved for the divine — creation, too, is called one. The uniqueness that belongs to God alone is carried by a second word, aḥad 112:1, and by the sentence lā ilāha illā huwa, «there is no god but He».

The argument from ruin
interpreted· aqlThe Qurʾān's own rational proof — read by the mutakallimūn as burhān al-tamānuʿ, the argument from mutual obstruction.
The Qurʾān does not only assert the One; it reasons to it. Twice it runs the same argument: if there were more than one god, the order we see could not hold. In 21:22: «Had there been in them gods besides God, both would have been ruined» — a divided will over one cosmos yields not order but collapse. In 23:91: «each god would have taken away what it created, and some would have overcome others» — plural sovereignty fractures into rivalry. The unity of the world is offered as evidence for the unity of its Author. This is a claim you can test by ʿaql, reason — which is why it is badged not as counted fact but as argument.
The proof, in the text
interpreted· aqlTwo āyāt carrying the rational argument for oneness.
لَوْ كَانَ فِيهِمَآ ءَالِهَةٌ إِلَّا ٱللَّهُ لَفَسَدَتَا فَسُبْحَٰنَ ٱللَّهِ رَبِّ ٱلْعَرْشِ عَمَّا يَصِفُونَ
Had there been within the heavens and earth gods besides Allah, they both would have been ruined. So exalted is Allah, Lord of the Throne, above what they describe.
One will, one cosmos: divide the will and the cosmos falls apart.
مَا ٱتَّخَذَ ٱللَّهُ مِن وَلَدٍ وَمَا كَانَ مَعَهُۥ مِنْ إِلَٰهٍ إِذًا لَّذَهَبَ كُلُّ إِلَٰهٍۭ بِمَا خَلَقَ وَلَعَلَا بَعْضُهُمْ عَلَىٰ بَعْضٍ سُبْحَٰنَ ٱللَّهِ عَمَّا يَصِفُونَ
Allah has not taken any son, nor has there ever been with Him any deity. [If there had been], then each deity would have taken what it created, and some of them would have sought to overcome others. Exalted is Allah above what they describe [concerning Him].
Plural gods would not cooperate — each would seize its own and clash with the rest.
Where oneness and its denial meet
interpreted· quran by quranIn 8 verses the two roots collide in one āya. The clearest is 18:110, where oneness of belief becomes non-association in worship.
Tawḥīd — «one God»
إِلَٰهٌ وَٰحِدٌThat there is one God — and that worship is owed to Him alone.
- «Your God is one God» — and so «let him not associate anyone in the worship of his Lord» 18:110.
- «He is but one God, and I am free of what you associate» 6:19 — affirmation and disavowal in one breath.
- Belief in oneness (tawḥīd) and its practice (worship of the One) are the same claim seen from two sides.
Shirk — «associating»
الشِّرْكSetting up a rival to God — in lordship, in worship, or in obedience.
- Its commonest form is a verb: ashraka, «he associated», 71× — shirk is something one does, not merely thinks.
- It can be subtle: taking «scholars and monks as lords besides God» 9:31 — obeying a creature as one obeys the Creator.
- It is the one sin the Qurʾān says God «does not forgive» if one dies upon it 4:48 — because it denies the ground of everything else.
One question
interpreted· aqlTest your reading
In 21:22 the Qurʾān argues that if there were other gods, «both would have been ruined» (lafasadatā). What does that argument take as its evidence?
What oneness rules out
interpreted· quran by quranThe tradition names dimensions of tawḥīd; each answers a form of shirk the Qurʾān actually addresses.
Oneness in Lordship
توحيد الربوبيةOne Creator and Sustainer of all — «Who is Lord of the heavens and earth? Say: God» 13:16.
Oneness in Worship
توحيد العبادةWorship owed to Him alone — «do not take two deities» 16:51; «worship none but one God» 9:31.
Oneness of the Divine Self
توحيد الذاتNo parts, no peer, no offspring — «He neither begets nor is begotten, and none is comparable to Him» 112:3.
Is God's knowledge God, or something added to Him?
interpreted· aqlA genuine theological fork within tawḥīd — the oneness of the divine attributes (tawḥīd al-ṣifāt). Both readings affirm the One; they differ on how the attributes relate to the Essence.
When the Qurʾān calls God «Knowing», «Living», «Powerful» — are these attributes identical with His Essence, or realities added to it?
Reading AThe attributes are the Essence (ʿaynu'l-dhāt)
عينية الصفاتGod's knowledge, life, and power are not things besides Him; they are Him, named from different vantage points. To make them additional realities would be to multiply the eternal — a hidden shirk.
- Held by the Imāmī and Muʿtazilī theologians: absolute oneness forbids any real multiplicity in the divine.
- «There is nothing comparable to Him» 112:4 is read to exclude even an internal composition of Essence-plus-attributes.
Reading BThe attributes are additional to the Essence
زيادة الصفاتGod really has knowledge, life, power — eternal attributes subsisting in Him, distinct in meaning though never separate. To collapse them into the Essence, this reading warns, empties the divine names of content.
- Held by the Ashʿarī theologians: the attributes are «neither He nor other than He».
- The plain sense of the many names is honoured rather than reinterpreted.
The atlas records the fork — it crowns no reading.

Oneness declared
interpreted· quran by quranSix of the Qurʾān's great declarations of the One.
وَإِلَٰهُكُمْ إِلَٰهٌ وَٰحِدٌ لَّآ إِلَٰهَ إِلَّا هُوَ ٱلرَّحْمَٰنُ ٱلرَّحِيمُ
And your god is one God. There is no deity [worthy of worship] except Him, the Entirely Merciful, the Especially Merciful.
«Your God is one God; there is no god but He, the Merciful, the Compassionate.»
ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ لَا تَأْخُذُهُۥ سِنَةٌ وَلَا نَوْمٌ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُۥٓ إِلَّا بِإِذْنِهِۦ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَىْءٍ مِّنْ عِلْمِهِۦٓ إِلَّا بِمَا شَآءَ وَسِعَ كُرْسِيُّهُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَلَا يَـُٔودُهُۥ حِفْظُهُمَا وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُ
Allah - there is no deity except Him, the Ever-Living, the Sustainer of [all] existence. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursi extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great.
Āyat al-Kursī — the living, self-subsisting One whom no slumber overtakes.
شَهِدَ ٱللَّهُ أَنَّهُۥ لَآ إِلَٰهَ إِلَّا هُوَ وَٱلْمَلَٰٓئِكَةُ وَأُو۟لُوا۟ ٱلْعِلْمِ قَآئِمًۢا بِٱلْقِسْطِ لَآ إِلَٰهَ إِلَّا هُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ
Allah witnesses that there is no deity except Him, and [so do] the angels and those of knowledge - [that He is] maintaining [creation] in justice. There is no deity except Him, the Exalted in Might, the Wise.
God, the angels, and «those of knowledge» all witness the same truth.
وَقَالَ ٱللَّهُ لَا تَتَّخِذُوٓا۟ إِلَٰهَيْنِ ٱثْنَيْنِ إِنَّمَا هُوَ إِلَٰهٌ وَٰحِدٌ فَإِيَّٰىَ فَٱرْهَبُونِ
And Allah has said, "Do not take for yourselves two deities. He is but one God, so fear only Me."
«Do not take two deities» — the plainest command against dualism.
ذَٰلِكُم بِأَنَّهُۥٓ إِذَا دُعِىَ ٱللَّهُ وَحْدَهُۥ كَفَرْتُمْ وَإِن يُشْرَكْ بِهِۦ تُؤْمِنُوا۟ فَٱلْحُكْمُ لِلَّهِ ٱلْعَلِىِّ ٱلْكَبِيرِ
[They will be told], "That is because, when Allah was called upon alone, you disbelieved; but if others were associated with Him, you believed. So the judgement is with Allah, the Most High, the Grand."
Belief itself is tested at the point of oneness: they believed only when partners were named.
وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦ وَٱلْأَرْضُ جَمِيعًا قَبْضَتُهُۥ يَوْمَ ٱلْقِيَٰمَةِ وَٱلسَّمَٰوَٰتُ مَطْوِيَّٰتٌۢ بِيَمِينِهِۦ سُبْحَٰنَهُۥ وَتَعَٰلَىٰ عَمَّا يُشْرِكُونَ
They have not appraised Allah with true appraisal, while the earth entirely will be [within] His grip on the Day of Resurrection, and the heavens will be folded in His right hand. Exalted is He and high above what they associate with Him.
«They have not measured God with His true measure» — the whole earth in His grip.
The web tawḥīd sits in
interpreted· quran by quranOpposites drawn dashed. Oneness stands against association; it grounds sincere worship and the witness of knowledge; the divine names are its facets.
The One who is not lonely
interpreted· quran by quranThe Qurʾān argues for oneness the way it argues for little else — by reason 21:22, by disavowal 6:19, by four bare lines that the tradition weighs against a third of the whole 112:1. Yet the argument ends where argument cannot reach: aḥad, uniquely one, al-ṣamad, the one all things need and who needs none. What the mind proves — that a divided will would ruin the world — the heart is left to hold: that behind everything there is not a crowd, and not a void, but One. Where the tradition still turns is not whether God is one, but how His knowing and living and mercy are one with Him — a question the page holds open, because the text names the attributes without ranking them.
