Muhammad bin Sirin said: Sayyiduna al-Hakam bin Amr al-Ghifari and Sayyiduna Imran bin Husayn (may Allah be pleased with them both), or one of the two - and I think it was Imran (may Allah be pleased with him) - used to narrate that the Messenger of Allah (peace and blessings be upon him) said: "There is no obedience in disobedience to Allah." Then the other said: Allahu akbar, three times - or as he said.
