Musnad Ahmad 33:491

Hassan narrated to us, Ibn Lahi'ah narrated to us, Abu al-Zubayr narrated to us, from Jabir, who said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, saying: "If I live, if Allah wills, I will forbid that one be named Barakah, Yasar, or Nafi'—Jabir said: I do not know if he mentioned Rafi' or not—for it is said: 'Is Barakah here?' and it is said: 'No.' And it is said: 'Is Yasar here?' and it is said: 'No.'" He said: Then the Messenger of Allah, peace and blessings of Allah be upon him, passed away, and he did not forbid that. Umar then intended to forbid it, but then he left it.
