Saad bin Abu Waqqas reported,

Saad said, "Four verses of the Quran were revealed concerning me. I came upon a sword and brought it to the Prophet ﷺ.I said, "Messenger of Allah, award it to me as my share of the spoils."He said, "Put it down."Then he stood up, and the Prophet ﷺ said to him, "Put it back where you took it from."Then he stood up again and said, "Award it to me, Messenger of Allah."He said, "Put it down."So he stood up once more and said, "Messenger of Allah, award it to me. Am I to be treated like a man who has no worth?"The Prophet ﷺ said to him, "Put it back where you took it from."He said, "Then this verse was revealed, "They ask you about the spoils of war. Say, the spoils belong to Allah and the Messenger" [Anfal 8:1].

عن سعد بن أبي وقاص قال

نزلت في أربع آيات، أصبت سيفا فأتى به النبي ﷺ فقال: يا رسول الله نفلنيه فقال: ضعه، ثم قام، فقال له النبي ﷺ ضعه من حيث أخذته، ثم قام، فقال: نفلنيه يا رسول الله، فقال: ضعه فقام، فقال: يا رسول الله نفلنيه أأجعل كمن لا غناء له؟ فقال له النبي ﷺ: ضعه من حيث أخذته، قال: فنزلت هذه الآية {يسألونك عن الأنفال قل الأنفال لله والرسول}.
