وَقَالُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ءَايَةٌ مِّن رَّبِّهِۦ ۚ قُلْ إِنَّ ٱللَّهَ قَادِرٌ عَلَىٰٓ أَن يُنَزِّلَ ءَايَةً وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ

And they say: Why has not a sign been sent down to him from his Lord? Say: Surely Allah is able to send down a sign, but most of them do not know.
