Sayyiduna Abu Qatadah (may Allah be pleased with him) narrates: When the Muslims retreated on the day of Hunayn, I saw Sayyiduna Umar bin Khattab (may Allah be pleased with him) and asked,“What is happening?”He replied,“This is Allah’s decree.”Then, when the people returned, I came to the Messenger of Allah (peace and blessings be upon him), who was sitting among a group of companions, and he was saying:“Whoever kills someone with his own hand and presents evidence for it, then the spoils (salb) will belong to him.”I had seen a polytheist trying cunningly to kill a Muslim; I came from behind and cut off both his wrists. He attacked me, and I thought I would die, but he became weak due to blood loss and fell, so I struck his neck with my sword and killed him. When I stood up to testify, no one testified for me. Then, when I stood up a second time, still no one came, so the Messenger of Allah (peace and blessings be upon him) said:“Abu Qatadah! What happened?”I said,“O Messenger of Allah! I cut off a polytheist’s wrists and then killed him, but I have no witness.”A man said,“O Messenger of Allah! He has spoken the truth; his spoils are with me.”Sayyiduna Abu Bakr (may Allah be pleased with him) said to him,“By Allah! This wealth cannot be yours. A man who fought in defense of the Messenger of Allah (peace and blessings be upon him) and the Muslims—his spoils are his right.”So the Messenger of Allah (peace and blessings be upon him) said:“Abu Bakr has spoken the truth; give this wealth to Abu Qatadah.”Thus, I took that wealth, and the very first wealth I acquired in Madinah was what I bought from the price of that salb.
