حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ "عَلَى الْمَرْءِ الْمُسْلِمِ السَّمْعُ وَالطَّاعَةُ فِيمَا أَحَبَّ وَكَرِهَ إِلاَّ أَنْ يُؤْمَرَ بِمَعْصِيَةٍ فَإِنْ أُمِرَ بِمَعْصِيَةٍ فَلاَ سَمْعَ وَلاَ طَاعَةَ " .
Translation
It has been narrated on the authority of Ibn 'Umar that the Prophet (ﷺ) said
It is obligatory upon a Muslim that he should listen (to the ruler appointed over him) and obey him whether he likes it or not, except that he is ordered to do a sinful thing. If he is ordered to do a sinful act, a Muslim should neither listen to him nor should he obey his orders.
