Jabir continued, "We had a friend of ours with us whom we used to equip to go out to guard our mounts. I gave him what was necessary and then he turned about to go to the mounts and he was wearing two threadbare cloaks of his. The Messenger of Allah (ﷺ) looked at him and said, 'Does he have two garments other than these?' I said, 'Yes, Messenger of Allah. He has two garments in the bag.' I gave them to him. He said, 'Let him go and put them on.' I let him go to put them on. As he turned to go, the Messenger of Allah (ﷺ) exclaimed, 'May Allah strike his neck. Isn't that better for him?' He said (taking him literally), 'Messenger of Allah, in the way of Allah.' The Messenger of Allah (ﷺ) said, 'In the way of Allah.' " Jabir added, "The man was killed in the way of Allah."
