Abu Dawud Book 36, Hadith Number 4818.

Narated By As-Sa’ib : I came to the Prophet (PBUH). The people began to praise me and make a mention of me. The Apostle of Allah (PBUH) said: I know you, that is, he knew him. I said: My father and mother be sacrificed for you! you were my partner and how good a partner ; you neither disputed nor quarrelled.
