Jabir (May Allah be pleased with him) reported:
When the Messenger of Allah (ﷺ) made up his mind to go in an expedition, he would say to us, "O Muhajirin and the Ansar! There are among you such people who have no property and no kinsfolk. Let everyone of you take along with him two or three men. None of us had a spare animal we took rides by turn." So I took two or three men with me and I rode my camel by turn equally with them.[Abu Dawud].
