We entered upon Ubâda bin-while he was sick. We said, "May Allâh make you good and healthy. Will you tell us a Hadith you heard from the Prophet (ﷺ) and by which Allâh may make you benefit?" He said, "The Prophet (ﷺ) called us and we gave him the Bai'a pledge for Islâm, and-among the conditions on which he took the Bai'a pledge from us, was that-we were to listen and obey (the orders of a Muslim ruler) both at the time when we were active and at the time when we were tired, and at our difficult time and at our ease and to be obedient to the ruler and give him his right even if he did not give us our right, and not to fight against him unless we noticed him having open Kufr (disbelief) for which we would have a proof with us from Allâh." [9:179-O.B]
