al-Fatḥ 48:22

Wa law qātalakumu'lladhīna kafarū la-wallawu'l-adbāra thumma lā yajidūna waliyyan wa lā naṣīrā

"Had those who disbelieve fought you, they would surely have turned their backs and fled. Then they would have found neither protector nor helper."

لَوْ in Arabic is the particle of imtināʿ: it states a condition that did not come about, together with the consequence that therefore did not come about. "Had it been…, it would have been…"

And this is the most important point of the verse: there was no fighting.

In the event the sūra recounts, no fighting broke out. The verse sets this down not as a deficiency but as a datum, and builds a ruling upon it: had there been fighting, the outcome would have been this.

This is like the stance recorded at al-Wāqiʿa for the pattern law nashāʾu: the verse speaks not of something that happened but of what could have happened and did not.

What is the function of the sentence? I record this as my own reading: the sūra shuts off the possibility that the turning back should be read as an incapacity. The treaty did not come out of an inability to fight. The verse says this without opening it for debate, in a single conditional sentence.

And in saying it, it frames no boast. The subject of the sentence is the other side (la-wallaw — they would have turned); it does not say "you would have won". The difference is fine, but it agrees with the tone of the sūra: the outcome is tied not to whose strength was greater but to who was left without support.

وَلَّىٰ — root و-ل-ي. The two directions of this root were recorded at verse 16: both "to be near, to be a friend" and "to turn away".

دُبُر — root د-ب-ر: the back, the end of a thing. Tadbīr is from the same root — to think through the end of a matter. Mudabbir (the one who manages a matter), idbār (turning back), dābir (root, hindmost part).

Wallā'd-dubr is a settled idiom in Arabic for "to flee": to turn one's back.

And now the point of word order in the verse.

• la-وَلَّوُا۟ — they turned their backs — root و-ل-ي
• lā yajidūna وَلِيًّا — they would find no walī — the same root

The same root, in the same verse, in two different senses. The word for what they do in fleeing is the same as the word for what they cannot find.

I record this as a weave of words; not as a claim of miracle. But the effect in the word order is plain: for the one who turns his back, no side is left to turn to.

وَلِيّ and نَصِير — two different kinds of support.

The Qurʾān often uses these two as a pair (al-Baqara 2/107, 120; al-Tawba 9/116). Together they close off the two sources of support: neither the protection that comes from a structural bond, nor help that actually arrives.

It was recorded at al-Naṣr that the concrete sense of the root naṣr has to do with rain — what comes from above onto dry ground and brings it to life. To have no naṣīr is for that descent not to happen.
