During the battle of Al-Ahzab, I and 'Umar bin-Salama were kept behind with the women. Behold ! I saw (my father) Az-Zubair riding his horse, going to and coming from Banî Quraiza twice or thrice. So when I came back I said, "O my father ! I saw you going to and coming from Banî Quraiza? He said, "Did you really see me, O my son? I said, Yes. He said, Allâh's Messenger (ﷺ) said, 'Who will go to Banî Quraiza and bring me their news? So I went, and when I came back, Allâh's Messenger (ﷺ) mentioned for me both his parents saying, 'Let my father and mother be sacrificed for you. ' [5:66-0.B]
