It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that on the day of the Battle of Badr the Messenger of Allah (peace and blessings be upon him) said: "Whoever kills an enemy will receive such-and-such a reward." On that occasion the elderly men stood firm beneath the banners, while the young men hastened to kill the enemy and to acquire spoils. Then the elders said to the young men: Make us partners with you (in the spoils), for we were a support behind you, and had any harm befallen you, you would have fallen back to us. The young men refused, so they brought their dispute to the Messenger of Allah (peace and blessings be upon him). The narrator says that on this occasion this verse was revealed: "They ask you about the spoils of war" [Surah al-Anfal: 1] . So the spoils were divided equally among all of them. This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs (Bukhari and Muslim) did not record it.
