The Aws and Khazraj tribes boasted, and Aws said, "We have four individuals." Khazraj said, "We have four individuals as well." Aws said, "Among us is Sa'd bin Mu'adh, whose shaking caused the Throne of the Most Merciful to tremble. Among us is also Khuzaimah bin Thabit, whose testimony is equivalent to that of two men. Among us is Hanzala bin Al-Rabi', who was washed by the angels. Among us is also Asim bin Thabit bin Al-Aflah, who protected his backside." Khazraj said, "Among us are four individuals who gathered the Quran during the time of the Messenger of Allah ﷺ and no one else did so. They are Ubay bin Ka'b, Mu'adh bin Jabal, Zaid bin Thabit, and Abu Zaid." I asked Anas, "Who is Abu Zaid?" He replied, "One of my uncles."
