Messenger of Allah (PBUH) said, "The best of your rulers are those whom you love and who love you, and those who supplicate Allah in your favour and you supplicate Allah in their favour. The worst of your rulers are those whom you hate and who hate you; and whom you curse and who curse you." It was asked (by those who were present): "Should not we oppose them?" He said, "No, as long as they establish Salat; as long as they establish Salat in your midst."

[Muslim].

‘Auf b. Malik al-Ashja‘i reported God's Messenger as saying, “Your best imams are those whom you like and who like you, on whom you invoke blessings and who invoke blessings on you; and your worst imams are those whom you hate and who hate you, whom you curse and who curse you.” They asked God's Messenger whether in that event they should not depose them, but he replied, “No, as long as they observe the prayer among you; no, as long as they observe the prayer among you. If anyone has a governor whom he sees doing anything which is an act of disobedience to God, he must disapprove of the disobedience to God which he commits, but must never withdraw from obedience.” Muslim transmitted it.

The best of your rulers are those whom you love and who love you, upon whom you invoke God's blessings and who invoke His blessing upon you. And the worst of your rulers are those whom you hate and who hate you, who curse you and whom you curse. (Those present) said: Shouldn't we overthrow them at this? He said: No, as long as they establish prayer among you. No, as long as they establish prayer among you. Mind you! One who has a governor appointed over him and he finds that the governor indulges in an act of disobedience to God, he should condemn the governor's act, in disobedience to God, but should not withdraw himself from his obedience. Ibn Jabir said: Ruzaiq narrated to me this hadith. I asked him: Abu Miqdam, have you heard it from Muslim b. Qaraza or did he describe it to you and he heard it from 'Auf (b. Malik) and he transmitted this tradition of Allah's Messenger (may peace be upon him)? Upon this Ruzaiq sat upon his knees and facing the Qibla said: By Allah, besides Whom there is no other God, I heard it from Muslim b. Qaraza and he said that te had heard it from Auf (b. Malik) and he said that he had heard it from the Messenger of Allah (may peace be upon him).

The best of your rulers are those whom you love and who love you, who invoke God's blessings upon you and you invoke His blessings upon them. And the worst of your rulers are those whom you hate and who hate you and whom you curse and who curse you. It was asked (by those present): Shouldn't we overthrow them with the help of the sword? He said: No, as long as they establish prayer among you. If you then find anything detestable in them. You should hate their administration, but do not withdraw yourselves from their obedience.
