Musnad Ahmad 33:654

Hujayn and Yunus narrated to us, they said: Al-Layth ibn Sa’d narrated to us, from Abu al-Zubayr, from Jabir ibn Abdullah, that a slave of Hatib came to the Messenger of Allah, peace and blessings of Allah be upon him, complaining about Hatib. He said: "O Messenger of Allah, Hatib will surely enter the Fire." The Messenger of Allah, peace and blessings of Allah be upon him, said: "You have lied; he shall not enter it, for he witnessed Badr and al-Hudaybiyyah."
