Jabir b. '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 (may peace be upon him) 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.
