إِنَّمَا ٱلۡمُؤۡمِنُونَ ٱلَّذِينَ ءَامَنُواْ بِٱللَّهِ وَرَسُولِهِۦ وَإِذَا كَانُواْ مَعَهُۥ عَلَىٰٓ أَمۡرٖ جَامِعٖ لَّمۡ يَذۡهَبُواْ حَتَّىٰ يَسۡتَـٔۡذِنُوهُۚ إِنَّ ٱلَّذِينَ يَسۡتَـٔۡذِنُونَكَ أُوْلَـٰٓئِكَ ٱلَّذِينَ يُؤۡمِنُونَ بِٱللَّهِ وَرَسُولِهِۦۚ فَإِذَا ٱسۡتَـٔۡذَنُوكَ لِبَعۡضِ شَأۡنِهِمۡ فَأۡذَن لِّمَن شِئۡتَ مِنۡهُمۡ وَٱسۡتَغۡفِرۡ لَهُمُ ٱللَّهَۚ إِنَّ ٱللَّهَ غَفُورٞ رَّحِيمٞ
Only those are believers, who believe in Allah and His Messenger: when they are with him on a matter requiring collective action, they do not depart until they have asked for his leave; those who ask for thy leave are those who believe in Allah and His Messenger; so when they ask for thy leave, for some business of theirs, give leave to those of them whom thou wilt, and ask Allah for their forgiveness: for Allah is Oft-Forgiving, Most Merciful.
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
Deem not the summons of the Messenger among yourselves like the summons of one of you to another: Allah doth know those of you who slip away under shelter of some excuse: then let those beware who withstand the Messenger's order, lest some trial befall them, or a grievous penalty be inflicted on them.
