[Machine] "And Abu Al-Haytham ibn Al-Tayhan and As'ad ibn Zurarah said: We were among the first to embrace Islam from the Ansar in Makkah and among the first to meet the Messenger of Allah ﷺ before their people, and we arrived in Madinah because of that. Abu Al-Haytham witnessed Al-Aqabah along with the Muslims from the Ansar, and he was one of the twelve leaders, and there was no disagreement among them in that. The Messenger of Allah ﷺ fostered a brotherhood between Abu Al-Haytham ibn Al-Tayhan and Uthman ibn Mazh'un. Abu Al-Haytham also participated in the battles of Badr, Uhud, Al-Khandaq, and all other battles along with the Messenger of Allah ﷺ."
