فَمَا لَهُمْ لَا يُؤْمِنُونَ ۞ وَإِذَا قُرِئَ عَلَيْهِمُ الْقُرْآنُ لَا يَسْجُدُونَ
What is wrong with them that they do not believe, and when the Qurʾān is recited to them they do not bow? (84:20–21)
“Fa-mā lahum” is a question of rejection and rebuke, not a request for unknown information. The following conditional description illustrates one manifestation of refusal: rejecting submission even after hearing the Qurʾān. “Quriʾa” is passive, focusing on the recitation and the listener's response, not on the identity of a reciter.
“Lā yasjudūn” depicts a repeated or characteristic reaction. Distinguish a negative report about conduct from an interrogative rebuke directed at unbelief.
