Jabir bin 'Abdullah reported that a child was born to a person from the Ansar and he made up his mind to give him the name of Muhammad. He came to Allah's Apostle ( صلی اللہ علیہ وسلم ) and, asked him (about it), whereupon he said: The Ansar have done well to give the name (to your children) after my name, but do nct give them the kunya after my kunya.
