Saad bin Abu Waqqas reported,
I came to the Prophet ﷺ on the day of Badr carrying a sword and said, "Messenger of Allah, Allah has healed my heart today from the enemy, so grant me this sword."He replied, "This sword is neither mine nor yours."So I walked away saying to myself, "Today it will be given to someone who did not endure what I endured!"While I was in that state, the messenger came to me and said, "Answer the call."I thought something had been revealed concerning what I had said. When I came, the Prophet ﷺ said to me, "You asked me for this sword, and it was neither mine nor yours. Now Allah has given it to me, so it is yours."Then he recited, "They ask you about the spoils of war. Say, the spoils belong to Allah and the Messenger" [Anfal 8:1], to the end of the verse.

Hasanعن سعد بن أبي وقاص قال
جئت إلى النبي ﷺ يوم بدر بسيف، فقلت: يا رسول الله إن الله قد شفى صدري اليوم من العدو، فهب لي هذا السيف. قال: إن هذا السيف ليس لي ولا لك. فذهبت وأنا أقول: يعطاه اليوم من لم يبل بلائي! فبينا أنا، إذ جاءني الرسول، فقال: أجب. فظننت أنه نزل في شيء بكلامي، فجئت، فقال لي النبي ﷺ: إنك سألتني هذا السيف، وليس هو لي ولا لك، وإن الله قد جعله لي فهو لك، ثم قرأ{يسألونك عن الأنفال قل الأنفال لله والرسول} إلى آخر الآية.
Abu Dawud (2740) narrated it, and this is his wording, as did Tirmidhi (3079), Ahmad (1538), and Hakim (2/132), all of them through the route of Abu Bakr bin Ayyash, from Asim bin Bahdala, from Musab bin Saad, from Saad bin Abu Waqqas, who related it.Tirmidhi said, "This is a hasan sahih hadith."Hakim said, "This is a hadith with a sahih chain."I say, its chain is hasan because of Asim bin Bahdala, for his hadith is hasan.Abu Dawud said following the hadith (2740), "Ibn Masud's reading is, 'They ask you about the spoils'. It has been said that the statement of Allah 
, "Say, the spoils belong to Allah and the Messenger", is abrogated by the statement of Allah , "Know that whatever spoils you take, a fifth of it belongs to Allah and to the Messenger" [Anfal 8:41]. The spoils on that day belonged to the Prophet ﷺ, then Allah abrogated that ruling with the fifth."
