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.

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ عَلَى الْمَرْءِ الْمُسْلِمِ السَّمْعُ وَالطَّاعَةُ فِيمَا أَحَبَّ وَكَرِهَ إِلاَّ أَنْ يُؤْمَرَ بِمَعْصِيَةٍ فَإِنْ أُمِرَ بِمَعْصِيَةٍ فَلاَ سَمْعَ وَلاَ طَاعَةَ
