Musannaf Ibn Abi Shayba 37:614

Abdullah ibn Numayr narrated to us, he said: Isma'il ibn Abi Khalid narrated to us, from Isma'il al-Awdi, who said: The daughter of Ma'qil ibn Yasar informed me that her father became severely ill. This reached Ibn Ziyad, so he came to visit him. He sat down and recognized death in him. He said to him: "O Ma'qil, will you not narrate to us? For Allah used to benefit us with things we heard from you." He said: "I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: 'There is no governor who governs a nation, whether few or many, and does not act justly among them, except that Allah will cast him upon his face into the Fire.'" The other [Ibn Ziyad] lowered his head for a while, then said: "Is this something you heard from the Messenger of Allah (peace and blessings of Allah be upon him), or from behind, behind [i.e., from someone else]?" He said: "No, rather it is something I heard from the Messenger of Allah (peace and blessings of Allah be upon him). I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: 'Whoever is entrusted with a flock and does not look after them with sincerity will not find the scent of Paradise, and its scent is found from a distance of a hundred years.'" Ibn Ziyad said: "Why did you not narrate this to me before now?" He said: "And now, were it not for the state I am in, I would not have narrated it to you."
