Abu Qatada reported,

We set out with the Prophet ﷺ in the year of Hunayn. When we met the enemy, the Muslims gave way for a moment. I saw a man from the polytheists overpowering one of the Muslims, so I struck him from behind on the muscle between his neck and shoulder with my sword, cutting through his armor. He turned on me and crushed me in such an embrace that I smelled the scent of death. Then death overtook him and he released me.I caught up with Umar bin Khattab and asked, "What is the matter with the people?"He replied, "It is the decree of Allah ."Then the people returned, and the Prophet ﷺ sat down and said, "Whoever has killed an enemy and can produce evidence for it, the spoils of the slain are his."I stood up and said, "Who will testify for me?" Then I sat down.The Prophet ﷺ repeated the same words. I stood up again and said, "Who will testify for me?" Then I sat down.The Prophet ﷺ said it a third time, so I stood up.He asked, "What is the matter with you, Abu Qatada?"I told him what had happened, and a man said, "He is telling the truth, and the spoils are with me, so satisfy him on my behalf."Abu Bakr said, "By Allah, no! He would never go to one of the lions of Allah who fights on behalf of Allah and His Messenger ﷺ and hand his spoils over to you."The Prophet ﷺ said, "He has spoken the truth, so give it to him."He gave it to me, and I sold it and bought a date grove among Banu Salama with the proceeds. It was the first property I acquired in Islam.

حدثنا عبد الله بن يوسف أخبرنا مالك عن يحيى بن سعيد عن عمر بن كثير بن أفلح عن أبي محمد مولى أبي قتادة

عن أبي قتادة قال

خرجنا مع النبي ﷺ عام حنين فلما التقينا كانت للمسلمين جولة فرأيت رجلا من المشركين قد علا رجلا من المسلمين فضربته من ورائه على حبل عاتقه بالسيف فقطعت الدرع وأقبل علي فضمني ضمة وجدت منها ريح الموت ثم أدركه الموت فأرسلني فلحقت عمر بن الخطاب فقلت ما بال الناس قال أمر الله عز وجل ثم رجعوا وجلس النبي ﷺ فقال من قتل قتيلا له عليه بينة فله سلبه فقلت من يشهد لي ثم جلست قال ثم قال النبي ﷺ مثله فقمت فقلت من يشهد لي ثم جلست قال ثم قال النبي ﷺ مثله فقمت فقال ما لك يا أبا قتادة فأخبرته فقال رجل صدق وسلبه عندي فأرضه مني فقال أبو بكر لاها الله إذا لا يعمد إلى أسد من أسد الله يقاتل عن الله ورسوله ﷺ فيعطيك سلبه فقال النبي ﷺ صدق فأعطه فأعطانيه فابتعت به مخرفا في بني سلمة فإنه لأول مال تأثلته في الإسلام
