وَيَقُولُ ٱلَّذِينَ كَفَرُواْ لَوۡلَآ أُنزِلَ عَلَيۡهِ ءَايَةٌ مِّن رَّبِّهِۦٓ ۗ إِنَّمَآ أَنتَ مُنذِرٌ ۖ وَلِكُلِّ قَوۡمٍ هَادٍ
And the Unbelievers say: "Why is not a sign sent down to him from his Lord?" But thou art truly a warner, and to every people a guide.<br/>
And those who disbelieve say, 'Why has not some sign been sent down upon him, upon Muhammad may peace and salutation be upon him, 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.
