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 ‏"‏ ‏.‏

It has been narrated on the authority of Ibn 'Umar that the Prophet (PBUH) 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. Translation Not Available
