Sahih Muslim Book 25, Hadith Number 5319.

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

Jabir b. Abdullah reported Allah’s Messenger (may peace be upon him) as saying: Give the name after my name, but do not give (the kunya of Abu’l-Qasim after my) kunya, for I am Abu’l-Qasim (in the sense) that I distribute amongst you (the spoils of war) and disseminate the knowledge (of revelation). This hadith has been transmitted on the authority of Abu Bakr but with a slight variation of wording.
