Sahih Adab al-Mufrad

743/961 (Sahih) [جابر] said: A son was born to so-and-so(1) from the Ansar, and he named him Muhammad. The Ansar said: We will not give you the kunya of the Messenger of Allah. Until we sat in the road asking him about the Hour. He said: "You have come to me asking me about the Hour?" We said: Yes. He said: "There is no soul that will reach one hundred years." We said: A son was born to so-and-so from the Ansar and he named him Muhammad, and the Ansar said: We will not give you the kunya of the Messenger of Allah. He said: "The Ansar have done well. Name (your children) with my name, but do not use my kunya."
