Narrated Abdullah ibn Umar: The Messenger of Allah (ﷺ) stood up, i.e. on the day of Badr, and said: Uthman has gone off on the business of Allah and His Apostle, and I shall take the oath of allegiance on his behalf. The Messenger of Allah (ﷺ) then allotted him a share, but did not do so for anyone else who was absent
