The reciter: Qutaybah ibn Sa'id narrated to us, Layth narrated to us from 'Ubayd Allah from Nafi' from Ibn 'Umar from the Prophet (peace and blessings be upon him) that he 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.
عَلَى الْمَرْءِ الْمُسْلِمِ السَّمْعُ وَالطَّاعَةُ فِيمَا أَحَبَّ وَكَرِهَ، إِلَّا أَنْ يُؤْمَرَ بِمَعْصِيَةٍ، فَإِنْ أُمِرَ بِمَعْصِيَةٍ، فَلَا سَمْعَ وَلَا طَاعَةَ Sahih Muslim 1839a.
