Al-An'am 6:37

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

Waqālū lawlā nuzzila ʿalayhi āyatun min rabbihi qul inna l-laha qādirun ʿalā an yunazzila āyatan walākinna aktharahum lā yaʿlamūna

And they say, "Why has a sign not been sent down to him from his Lord?" Say, "Indeed, Allāh is Able to send down a sign, but most of them do not know."
