Sahih Muslim Book 025, Hadith Number 5320.

Chapter : Forbiddance in calling one (other than Allah's Apostle) with the Kunya of Abdu'l-Qasim and the fact pertaining to good names.

This hadith has been reported on the authority of A'mash with the same chain of transmitters but there is a slight variation (of wording) that, instead of the word Bu'i that (I have been sent), the word ju'ilat (I have been made) has been used.
