أَمْ تُرِيدُونَ أَن تَسْـَٔلُوا۟ رَسُولَكُمْ كَمَا سُئِلَ مُوسَىٰ مِن قَبْلُ ۗ وَمَن يَتَبَدَّلِ ٱلْكُفْرَ بِٱلْإِيمَٰنِ فَقَدْ ضَلَّ سَوَآءَ ٱلسَّبِيلِ
Or would ye question your messenger as Moses was questioned aforetime? He who chooseth disbelief instead of faith, verily he hath gone astray from a plain road.
Surah Al-Baqara(2:108)
