﴿ وَقَالُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ءَايَةٌۭ مِّن رَّبِّهِۦ ۚ قُلْ إِنَّ ٱللَّهَ قَادِرٌ عَلَىٰٓ أَن يُنَزِّلَ ءَايَةًۭ وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ ﴾

“And they say, "Why has no miraculous sign been bestowed on him from on high by his Sustainer?" Say: "Behold, God has the power to bestow any sign from on high." Yet most human beings are unaware of this”
