4187. 'Abdullāh bin 'Umar added, "The people were along with the Prophet ﷺ on the day of Al-Hudaibiya spreading in the shade of the trees. Suddenly the people surrounded the Prophet ﷺ and started looking at him." 'Umar said, "O 'Abdullāh! Go and see why the people are encircling Allāh's Messenger ﷺ and looking at him." 'Abdullāh bin 'Umar then saw the people giving the Bai'a to the Prophet ﷺ. So he also gave the Bai'a and returned to 'Umar, who went out in his turn and gave the Bai'a (to the Prophet ﷺ).
