Musannaf Ibn Abi Shaybah 35300 — Those who gave the belongings

Ibn Sirin (may Allah have mercy on him) reports that Sayyiduna Anas bin Malik (may Allah be pleased with him) said: A fifth used not to be collected from the property stripped from a slain man. The first fifth taken from a slain man's property in Islam was taken from the belongings of the man slain by Sayyiduna al-Bara bin Malik (may Allah be pleased with him). It happened in this way: he charged at the Marzuban of al-Zarah and struck him with a spear that went into one end of his saddle. Then he came up to him, cut off his belt and his bracelets and took them. He said: When we returned to Madinah, Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) led the morning prayer. Then he came to us and, after giving the greeting of peace, asked: "Is Abu Talhah here?" He said: "Yes, I am here." And he came out to Sayyiduna Umar (may Allah be pleased with him). Sayyiduna Umar (may Allah be pleased with him) then said: "We do not take a fifth from the property stripped from a slain man, but the belongings of al-Bara's slain man are a very great amount of wealth, and I will certainly take its fifth." So he called for the appraisers, and they valued it at thirty thousand, and he collected six thousand from it.
