﴿ وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ ءَايَةٌۭ مِّن رَّبِّهِۦٓ ۗ إِنَّمَآ أَنتَ مُنذِرٌۭ ۖ وَلِكُلِّ قَوْمٍ هَادٍ ﴾

“However, they who are bent on denying the truth [refuse to believe and] say, "Why has no miraculous sign ever been bestowed on him from on high by his Sustainer?" [But] thou art only a warmer; and [in God] all people have a guide.”

And those who disbelieve say ‘Why has not some sign been sent down upon him upon Muhammad (s) from his Lord!’ the like of the staff and the glowing hand or the she-camel. God exalted be He says You are only a warner one to threaten the disbelievers for it is not your duty to bring forth signs; and for every folk there is a guide a prophet to guide them to their Lord with the signs that He gives him and not what with they request.
