It has been narrated on the authority of Abu Malik that Ubaidullah bin Ziyad visited Maqil bin Yaser in the latters illness. Maqil said to him: I am narrating to you a tradition. If I were not at deaths 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.
