And they say, "Why has a sign not been sent down to him from his Lord?" Say, "Indeed, Allah is Able to send down a sign, but most of them do not know."
The Saheeh International Quran Translation
وَقَالُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ءَايَةٌ مِّن رَّبِّهِۦ قُلْ إِنَّ ٱللَّهَ قَادِرٌ عَلَىٰٓ أَن يُنَزِّلَ ءَايَةً وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَAnd they say, "Why has a sign not been sent down to him from his Lord?" Say, "Indeed, Allah is Able to send down a sign, but most of them do not know."
