A hadith has been narrated by Mus'ab b. Sa'd who heard it from his father as saying:" Four verses of the Qur'an have been revealed about me. I found a sword (among the spoils of war). It was brought to Prophet ﷺ. He (my father) said: Messenger of Allah, bestow it upon me. The Apostle of Allah ﷺ said: Place it there. Then he (my father) stood up and the Messenger of Allah ﷺ said to him: Place it from where you got it. (At this) he (my father) said again: Messenger of Allah, bestow it upon me Shall I be treated like one who has no share in (the booty)? The Apostle of Allah (may peace be upon him said: Place it from where you got it. At this was revealed the verse:" They ask thee about the spoils of war.... Say: The spoils of war are for Allah and the Messenger"
