Abu Qatada reported

We accompanied the Messenger of Allah (my peace be upon him) on an expedition in the year of the Battle of Hunain. When we encountered the enemy, (some of the Muslims turned back (in fear). I saw that a man from the polytheists overpowered one of the Muslims. I turned round and attacked him from behind giving a blow between his neck and shoulder. He turned towards me and grappled with me in such a way that I began to see death staring me in the face. Then death overtook him and left me alone. I joined 'Umar b. al-Khattab who was saying: What has happened to the people (that they are retreating)? I said: It is the Decree of Allah. Then the people returned. (The battle ended in a victory for the Muslims) and the Messenger of Allah (ﷺ) sat down (to distribute the spoils of war). He said: One who has killed an enemy and can bring evidence to prove it will get his belongings. So I stood up and said: Who will give evidence for me? Then I sat down. Then he (the Holy Prophet ) said like this. I stood up (again) and said: Who will bear witness for me? He (the Holy Prophet) made the same observation the third time, and I stood up (once again). Now the Messenger of Allah (ﷺ) said: What has happened to you, O Abu Qatada? Then I related the (whole) story, to him. At this, one of the people said: He has told the truth. Messenger of Allah 1 The belongings of the enemy killed by him are with me. Persuade him to forgo his right (in my favour). (Objecting to this proposal) Abu Bakr said: BY Allah, this will not happen. The Messenger of Allah (ﷺ) will not like to deprive one of the lions from among the lions of Allah who fight in the cause of Allah and His Messenger and give thee his share of the booty. So the Messenger of Allah (may peace he upon him) said: He (Abu Bakr) has told the truth, and so give the belongings to him (Abu Qatada). So he gave them to me. I sold the armour (which was a part of my share of the booty) and bought with the sale proceeds a garden in the street of Banu Salama. This was the first property I acquired after embracing Islam. In a version of the hadith narrated by Laith, the words uttered by Abu Bakr are:" No, never! He will not give it to a fox from the Quraish leaving aside a lion from the lions of Allah among...." And the hadith is closed with the words:" The first property I acquired."
