Sayyiduna Amr al-Bikali (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) saying: "When there are rulers over you who command you to pray, to wage jihad and to give zakah, then reviling them is forbidden to you, and praying behind them is lawful for you."
This narration has been recorded by Imam al-Tabarani.
