Musnad Abu Ya'la al-Mawsili 108:148

A boy was born to a man among us, and he named him Muhammad. His people said to him, "We will not let you name him with the name of the Messenger of Allah, may Allah bless him and grant him peace." So he set off with his son, carrying him on his back, and brought him to the Messenger of Allah, may Allah bless him and grant him peace. He said, "O Messenger of Allah, a boy was born to me, and I named him Muhammad. My people said to me, 'We will not let you name him with the name of the Messenger of Allah, may Allah bless him and grant him peace.'" He said, "Name yourselves with my name, but do not use my kunya (patronymic), for I am only a distributor, distributing among you."
