Musannaf Ibn Abi Shayba 33:1296

Affan narrated to us, he said: Sulayman narrated to us, from Thabit, who said: Mutarrif said: A man saw me and Mudh'ur and said, "Whoever is pleased to look at two men from the people of Paradise, let him look at these two." Mudh'ur heard it, and I saw the dislike on his face. Then he said, "O Allah, You know us, and we do not know ourselves."
