Musannaf Ibn Abi Shayba 33:1505

Yazid ibn Harun narrated to us, he said: Al-Jurayri informed us, from Abu Nadra, that a man entered Paradise and saw a slave of his above him like a star. He said: "O my Lord, by Allah, this was my slave in the world, so what brought him down to this position?" He said: "He was better in deeds than you."
