A hadith has been narrated by Mus'ab b. Sa'd who heard it from his father as saying: My father took a sword from Khums and brought it to Prophet ﷺ and said: Grant it to me. He refused. At this Allah revealed (the Qur'anic verse):" They ask thee concerning the spoils of war. Say: The spoils of war are for Allah and the Apostle" (viii. 1).

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ سِمَاكٍ، عَنْ مُصْعَبِ بْنِ سَعْدٍ، عَنْ أَبِيهِ، قَالَ أَخَذَ أَبِي مِنَ الْخُمْسِ سَيْفًا فَأَتَى بِهِ النَّبِيَّ ﷺ فَقَالَ هَبْ لِي هَذَا . فَأَبَى فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ { يَسْأَلُونَكَ عَنِ الأَنْفَالِ قُلِ الأَنْفَالُ لِلَّهِ وَالرَّسُولِ}
