Ghalib al-Qattan quoted a man who stated on the authority of his father that his grandfather reported God’s Messenger as saying, “The office of a chief is necessary, for people must have chiefs, but the chiefs will go to hell.”*
Abu Dawud transmitted it.
* Mirqat. iv, 133 says this means those who are unjust, or is a warning against the temptations to injustice arising from their office.
