Enjoin what is good and forbid what is evil before the worst amongst you are given authority over you and then when even the best of you make dua against them, their duas will not be accepted.
Uthman ibn AffanIf anyone stumbles then he must repent. If anyone errs then he must repent. And no one must insist on (the path of) destruction. If anyone insists on tyranny then he is far away from the path
