Chapter : Regarding the right of the fighter to the belongings of the one killed by him in the fight.

It has been reported by Salama b. al-Akwa': We fought the Battle of Hawazin along with the Messenger of Allah (may peace be upon him), (One day) when we were having our breakfast with the Messenger of Allah (may peace he upon him), a man came riding a red camel. He made it kneel down, extracted a strip of leather from its girth and tethered the camel with it. Then he began to take food with the people and look (curiously around). We were in a poor condition as some of us were on foot (being without any riding animals). All of a sudden, he left us hurriedly, came to his camel, made it kneel down, mounted it and urged the beast which ran off with him. A man on a brown she-camel chased him (taking him for a spy). Salama (the narrator) said: I followed on foot. I ran on until I was near the thigh of the she-camel. I advanced further until I was near the haunches of the camel. I advanced still further until I caught hold of the nose-string of the camel. I made it kneel down. As soon as it placed its knee on the ground, I drew my sword and struck at the head, of the rider who fell down. I brought the camel driving it along with the man's baggage and weapons. The Messenger of Allah (may peace be upon him) came forward to meet me and the people were with him. He asked: Who has killed the man? The people said: Ibn Akwa'. He said: Everything of the man is for him (Ibn Akwa').
