Junadah bin Abi Umayyah says that we went to Hazrat Ubadah bin Samit (may Allah be pleased with him), he was ill. We said: May Allah grant you health, please narrate a hadith from which Allah may benefit you. (He narrated that) I heard from the Prophet Muhammad (peace be upon him) on the night of Aqabah, that he called us and we pledged allegiance to him. Among the things that the Prophet (peace be upon him) took a covenant from us was that we would obey and follow in happiness and displeasure, in hardship and ease, and even when our rights are denied, and also that we would not dispute with the rulers regarding authority unless we see open disbelief from them; if they commit open disbelief, then you will have a proof with Allah.
