"I gave the Bai'a (pledge) (Ar-Ridwan) to Allâh's Messenger (ﷺ) and then I moved to the shade of a tree. When the number of people around the Prophet (ﷺ) diminished, he said, 'O Ibn Al-Akwa ' ! Will you not give to me the Bai'a (pledge)? ' I replied, 'O Allâh's Messenger (ﷺ)! I have already given to you the Bai'a (pledge). ' He said, 'Do it again. ' So I gave the Bai‘a (pledge) for the second time." He was asked, "O Abu Muslim ! For what did you give the Bai'a (pledge) on that day?" He replied, "We gave the Bai'a (pledge) for death."
