حَدَّثَنَا أَسْوَدُ بْنُ عَامِرٍ أَنْبَأَنَا أَبُو بَكْرٍ عَنْ عَاصِمِ بْنِ أَبِي النَّجُودِ عَنْ مُصْعَبِ بْنِ سَعْدٍ عَنْ سَعْدِ بْنِ مَالِكٍ قَالَ قَالَ يَا رَسُولَ اللَّهِ قَدْ شَفَانِي اللَّهُ مِنْ الْمُشْرِكِينَ فَهَبْ لِي هَذَا السَّيْفُ قَالَ إِنَّ هَذَا السَّيْفَ لَيْسَ لَكَ وَلَا لِي ضَعْهُ قَالَ فَوَضَعْتُهُ ثُمَّ رَجَعْتُ قُلْتُ عَسَى أَنْ يُعْطَى هَذَا السَّيْفُ الْيَوْمَ مَنْ لَمْ يُبْلِ بَلَائِي قَالَ إِذَا رَجُلٌ يَدْعُونِي مِنْ وَرَائِي قَالَ قُلْتُ قَدْ أُنْزِلَ فِيَّ شَيْءٌ قَالَ كُنْتَ سَأَلْتَنِي السَّيْفَ وَلَيْسَ هُوَ لِي وَإِنَّهُ قَدْ وُهِبَ لِي فَهُوَ لَكَ قَالَ وَأُنْزِلَتْ هَذِهِ الْآيَةُ يَسْأَلُونَكَ عَنْ الْأَنْفَالِ قُلْ الْأَنْفَالُ لِلَّهِ وَالرَّسُولِ
مسند امام احمد بن حنبل · Hadith 1538
It was narrated from Mus'ab bin Saad that Saad bin Malik said: O Messenger of Allah, I feel joy because Allah enabled me to wreak vengeance on the mushrikeen ; grant me this sword. He said: "This sword is not for you and it is not for me; leave it alone," So I put it down, then I came back and said: Perhaps this sword will be given today to someone who did not do as well as me. Then I heard a man calling me from behind and I said: Has something been revealed concerning me? He said; You asked me about the sword, and it was not mine. But now it has been granted to me, and it is yours." And he said: This verse was revealed interpretation of the meaning): They ask you (O Muhammad (PBUH) about the spoils of war,say: The spoils are for Allah and the Messenger" [al-Anfal 8:1].
