Mutayr went out to perform Hajj. When they were at al-Suwayda', a man came as if looking for medicine or for hudad (a medicinal extract), and said: The one who heard the Messenger of Allah (peace and blessings be upon him) informed me that during the Farewell Hajj he (peace and blessings be upon him) was admonishing the people, enjoining good upon them and forbidding them from evil, and he (peace and blessings be upon him) said: "O people! Take the stipend (of the ruler) as long as it is a stipend; but when Quraysh fight one another over kingship, and it comes at the cost of one of you's religion, then leave it."
