Al An'am, 37 Ayah
6:37
وَقَالُواْ لَوۡلَا نُزِّلَ عَلَيۡهِ ءَايَةٞ مِّن رَّبِّهِۦۚ قُلۡ إِنَّ ٱللَّهَ قَادِرٌ عَلَىٰٓ أَن يُنَزِّلَ ءَايَةٗ وَلَٰكِنَّ أَكۡثَرَهُمۡ لَا يَعۡلَمُونَ ٣٧
Wa Qālū Lawlā Nuzzila `Alayhi 'Āyatun Min Rabbihi ۚ Qul 'Inna Al-Laha Qādirun `Alá 'An Yunazzila 'Āyatan Wa Lakinna 'Aktharahum Lā Ya`lamūna
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."
