Musnad Ahmad 33:369

Hajjaj narrated to us, Ibn Jurayj narrated to us, Abu al-Zubayr informed me that he heard Jabir saying: A slave of Hatib ibn Abi Balta'ah—one of the Banu Asad—came complaining about his master. He said: "By Allah, O Messenger of Allah, Hatib will surely enter the Fire." The Messenger of Allah, peace and blessings of Allah be upon him, said to him: "You have lied. He will never enter it, for he witnessed Badr and al-Hudaybiyyah."
