From Sahih Muslim:
(21) Anas reported that person at Baqi' called another person as"
Abu'l-
Qasim," and Allah's Messenger (may peace be upon him) turned towards him. He (the person who had uttered these words) said: Messenger of Allah, I did not mean you, but I called such and such (person), whereupon Allah's Messenger (may peace be upon him) said: You may call yourself by my name, but not by my kunya. (Book
#025, Hadith
#5314)
(22) 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. (Book
#025, Hadith
#5319)
(23) Jabir b. 'Abdullah reported: A child was born in the house of a person amongst us, and he gave him the name of
Qasim. We said: We will not allow you (to give the name) to your child as
Qasim (and thus adopt the kunya of
Abu'l-
Qasim) and coal your eyes. He (that person) came to Allah's Apostle (may peace be upon him) and made a mention of that to him, whereupon he said: Call your son 'Abd al-Rahman. (Book
#025, Hadith
#5323)
(24)
Abu Huraira reported that
Abu'l-
Qasim (may peace be upon him) said: Give name (to your children) after my name but do not give the kunya (of
Abu'l-
Qasim) after my kunya. 'Amr reported from
Abu Huraira that he did not say that he had heard it directly from Allah's Apostle (may peace be upon him). (Book
#025, Hadith
