Musnad Ahmad 26:86

Abu Mu’awiyah—meaning Ibn ‘Amr—narrated to us, Zaidah narrated to us, and he mentioned the like of it, except that he said: "Except Suhayl ibn Bayda." And he said regarding the statement of Abu Bakr, he said: Abu Bakr said: "O Messenger of Allah, your kin, your lineage, and your people; overlook them, for Allah may save them from the Fire through you." He said: And Abdullah ibn Rawahah said: "O Messenger of Allah, you are in a valley with much firewood, so ignite it with fire, then cast them into it." Al-Abbas said: "May Allah sever your ties of kinship."
