وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ ٱلْكَذِبَ وَهُوَ يُدْعَىٰٓ إِلَى ٱلْإِسْلَٰمِ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ
Wa man aẓlamu mimmani'ftarā ʿala'llāhi'l-kadhiba wa huwa yudʿā ila'l-Islām, wa'llāhu lā yahdi'l-qawma'ẓ-ẓālimīn
"Who does greater wrong than one who fabricates a lie about God while he is being called to Islam? God does not guide the wrongdoing people."
This pattern was treated at al-Baqara 2/114. What was recorded there was this: the heaviest attribute (aẓlam — "more wrongdoing") is attached to a single deed, and the expression is kept general; it is not reduced to a particular event.
What is to be added here is the interrogative form of the pattern. "Who could do greater wrong?" — in grammar this is the kind of question called istifhām inkārī: it expects no answer, it states that the answer is "no one". The sentence, then, is really a judgement of the superlative, in the guise of a question.
And the distribution of the pattern in the Qurʾān is worth noting: each time it is attached to a different deed — hindering access to the places of worship (2/114), fabricating a lie about God, turning away from the verses, concealing testimony. The ruling "the greatest wrongdoer", then, is not assigned to a single offence.
This shows how the pattern is to be understood: each of them marks the deed at the extreme within its own field. It is not a competition but the establishing of a category.
From this ٱفْتِرَاء is born: to fabricate a thing by cutting and shaping it. Fabrication, then, in the language's own logic, is a manufacture: raw material is taken, it is worked, and a product comes out.
This is the most important idea the word carries. Fabrication is not a mistake but a production. To be mistaken is passive; to fabricate is active. And the thing produced has a form — not a random utterance but something cut out, sewn, ready to be presented.
عَلَى ٱللَّهِ — "about God / against God". The particle ʿalā here states being against: what is fabricated is ascribed to God.
And this is the finest point of the verse. The sentence ends with a circumstantial clause: "…while he is being called."
This caveat is what aggravates the offence. And it works like this: to manufacture a fabrication is an offence in any case; but to manufacture a fabrication while the door stands open is another thing.
The verse, then, establishes a point about timing. Two roads lie before the person and both are open: to follow the call, or to manufacture an alternative. He chooses the second. The gravity of the offence comes from the first having been within reach.
This is a relative of the point established in Sūrat al-Bayyina. There it was shown that the division came not from ignorance but after the proof had arrived. Here too the fabrication is made not in the absence of the call but in its presence.
يُدْعَىٰ — passive. Who is calling is not said. This widens the scope of the verse: what matters is not the agent of the call but its existence. If the door is open, it makes no difference who opened it.
ٱلْإِسْلَٰم — root س-ل-م. As was analysed in the section on al-Baqara 2/130-132, this root carries both the sense to submit and the sense to be sound, to be in well-being; and as was recorded there, in the story of Abraham (Ibrāhīm) the word occurs not as the name of a religion but as a deed.
ظَالِم — root ظ-ل-م. As was analysed in the section on al-Mumtaḥana, the root has two senses: darkness and putting a thing somewhere other than its own place.
The second sense is exactly apt in this verse. What is fabrication? Putting a word where it does not belong — ascribing to God something a human being produced. The offence, then, in the word's own logic, is an offence of displacement.
And this speaks quietly with the second verse of the sūra. There word and deed diverged; here the word is separated from its owner and ascribed to another. Both deeds produce a disconnection: in the one between the speaker and the doer, in the other between the word and its source.
