The Book on Government
33/16. Chapter:
The obligation to denounce rulers for that in which they go against Shari'ah, but they should not be fought so long as they pray regularly, etc
Sahih Muslim
وَحَدَّثَنِي أَبُو الرَّبِيعِ الْعَتَكِيُّ، حَدَّثَنَا حَمَّادٌ، - يَعْنِي ابْنَ زَيْدٍ - حَدَّثَنَا الْمُعَلَّى بْنُ، زِيَادٍ وَهِشَامٌ عَنِ الْحَسَنِ، عَنْ ضَبَّةَ بْنِ مِحْصَنٍ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم . بِنَحْوِ ذَلِكَ غَيْرَ أَنَّهُ قَالَ " فَمَنْ أَنْكَرَ فَقَدْ بَرِئَ وَمَنْ كَرِهَ فَقَدْ سَلِمَ " .
Another version of the tradition narrated on the same authority attributes the same words to the Messenger of Allah (ﷺ) except that it replaces kariha with ankhara and vice versa.
