Narrated by Jabir bin 'Abdullah
On the day of Al-Hudaibiya, Allah's Apostle said to us' "You are the best people on the earth!" We were 1400 then. If I could see now, I would have shown you the place of the Tree (beneath which the Pledge of allegiance was given by us)," Salim said, "Our number was 1400." 'Abdullah bin Abi Aufa said, "The people (who gave the Pledge of allegiance) under the Tree numbered 1300 and the number of Bani Aslam was 1/8 of the Emigrants."
