The Prohibition Of Taking The Kunyah Abul-Qasim, And The Names Which Are Recommended
Jabir b. 'Abdullah reported that a child was born to one of the persons amongst us and he decided to give him the name of Muhammad We said: We will not allow you to give the name after the name of Allah's Messenger (ﷺ) until you ask him (the Prophet). So he (that person) came and said (to the Prophet): A child was born in my house and I wanted to give him the name (of Muhammad) after the name of Allah's Messenger (ﷺ) , whereas my people did not allow me that I should name him after that (sacred) name until I have asked Allah's Messenger (ﷺ) in this connection, whereupon he said: Give him the name after my name, but do not call him by my kunya, for I have been sent as a Qasim as I distribute amongst you.
