Musnad Ahmad 33:248

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, from Salim, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Name yourselves with my name, but do not use my kunya (patronymic), for I have been made a Qasim (distributor) who distributes among you."
