‘Urwah (rahimahullah) narrates that Hazrat ‘Abdullah bin Zubair (radhiyallahu ‘anhu) once said to his father, Hazrat Zubair (radhiyallahu ‘anhu), “O my father! I saw you attacking the disbelievers astride your red horse during the Battle of Khandaq.” Hazrat Zubair (radhiyallahu ‘anhu) replied, “O my son! Did you really see me at that time?” When Hazrat ‘Abdullah bin Zubair (radhiyallahu ‘anhu) replied in the affirmative, Hazrat Zubair (radhiyallahu ‘anhu) said, “Indeed on that day, Rasulullah (sallallahu ‘alaihi wasallam) gathered both his parents in the du‘aa he made for me saying, ‘Fire (the arrows, O Zubair)! May my father and mother be sacrificed for you!’”
