My father took a sword from Khums and brought it to the 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).
أَخَذَ أَبِي مِنَ الْخُمْسِ سَيْفًا فَأَتَى بِهِ النَّبِيَّ ﷺ فَقَالَ هَبْ لِي هَذَا فَأَبَى فَأَنْزَلَ اللَّهُ ﷻ { يَسْأَلُونَكَ عَنِ الأَنْفَالِ قُلِ الأَنْفَالُ لِلَّهِ وَالرَّسُولِ}
