Suwayd Bin Ghaflah reports that Umar Bin Al-Khattab (may Allah be pleased with him) once took him by the hand and said: “O Abu Umayyah, by Allah, I know not if we will meet again after today. Fear and obey Allah your Lord until the Day of Resurrection, as if you see Him, and obey the ruler (imam) even if he is an Abyssinian slave: if he beats you, be patient; if he robs you, be patient and if he belittles you, be patient. And if he tells you [to do something] to the detriment of your religion (to sin), say: ‘I hear and obey, (but) my blood goes before my religion.' Never leave the main Muslim body (Al-Jama'ah).” – Ibn Zanjawayh, Kitab Al
