An-Nur 24:63

لَّا تَجۡعَلُواْ دُعَآءَ ٱلرَّسُولِ بَيۡنَكُمۡ كَدُعَآءِ بَعۡضِكُم بَعۡضٗاۚ قَدۡ يَعۡلَمُ ٱللَّهُ ٱلَّذِينَ يَتَسَلَّلُونَ مِنكُمۡ لِوَاذٗاۚ فَلۡيَحۡذَرِ ٱلَّذِينَ يُخَالِفُونَ عَنۡ أَمۡرِهِۦٓ أَن تُصِيبَهُمۡ فِتۡنَةٌ أَوۡ يُصِيبَهُمۡ عَذَابٌ أَلِيمٌ 63

Do not make [your] calling of the Messenger among yourselves as the call of one of you to another. Already Allah knows those of you who slip away, concealed by others. So let those beware who dissent from the Prophet's order, lest fitnah strike them or a painful punishment
