Regarding the verse "Those who responded to Allah and the Messenger after injury had struck them. For those among them who did good and feared Allah is a great reward" [Al Imran 3:172], she said to Urwa, "Son of my sister, your two fathers were among them, Zubayr and Abu Bakr. When the Messenger of Allah ﷺ suffered what he suffered on the day of Uhud and the polytheists withdrew from him, he feared they would return. He asked, 'Who will go after them?' Seventy men volunteered from among them, and Abu Bakr and Zubayr were among them."
{الذين استجابوا لله والرسول من بعد ما أصابهم القرح للذين أحسنوا منهم واتقوا أجر عظيم} [آل عمران: ١٧٢] قالت لعروة: يا بن أختي، كان أبواك منهم: الزبير وأبو بكر لما أصاب رسول الله ﷺ ما أصاب يوم أحد انصرف عنه المشركون، خاف أن يرجعوا قال: من يذهب في إثرهم؟ فانتدب منهم سبعون رجلا، قال: كان فيهم أبو بكر والزبير.
