It has been narrated on the authority of Abu Malik that Ubaidullah bin Ziyad visited Ma'qil bin Yaser in the latter's illness. Ma'qil said to him: I am narrating to you a tradition. If I were not at death's door, I would not narrate it to you. I heard the Messenger of Allah (ﷺ) say: A ruler who, having obtained control over the affairs of the Muslims, does not strive for their betterment and does not serve them sincerely shall not enter Paradise with them.
