Sahih al-Bukhari Hadith 3975

On the day of (the battle) of Al-Yarmuk, the companions of Allah's Messenger (ﷺ) said to Az-Zubair رضی اللہ عنہ , "Will you attack the enemy so that we shall attack them with you?" Az-Zubair رضی اللہ عنہ replied, "If I attack them, you people would not support me." They said, "No, we will support you." So Az-Zubair رضی اللہ عنہ attacked them (i.e. Byzantine) and pierced through their lines, and went beyond them and none of his companions was with him. Then he returned and the enemy got hold of the bridle of his (horse) and struck him two blows (with the sword) on his shoulder. Between these two wounds there was a scar caused by a blow, he had received on the day of Badr (battle). When I was a child I used to play with those scars by putting my fingers in them. On that day (my brother) "Abdullah bin Az-Zubair رضی اللہ عنہ was also with him and he was ten years old. Az-Zubair رضی اللہ عنہ had carried him on a horse and let him to the care of some men.
