Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) said: When the day of Badr came, I killed Sa’id bin Al-‘As and took his sword, which was called Dhu Al-Kataif. I came to the Messenger of Allah (peace and blessings be upon him), and he said: Go and put it in the spoils of war. So I went, and in my heart was a feeling that only Allah, the Mighty and Majestic, knows, because of killing my brother and losing the spoils of war. I had not gone far when Surah Al-Anfal was revealed, so the Messenger of Allah (peace and blessings be upon him) said: Go and take your sword.
