The Messenger of Allah (ﷺ) would give a third of the spoils after he would keep off the fifth.
Sunan Abi Dawud Book 15, Hadith 272
← Previous Hadith The Messenger of Allah (ﷺ) went out on the day of Badr along with three hundred and fifteen (men). The Messenger of Allah (ﷺ) said: O Allah, they are on foot, provide mount for them; O Allah , they are naked, clothe them; O Allah, they are hungry, provide food for them. Allah then bestowed victory on them. They returned when they were clothed. There was no man of them but he returned with one or two camels; they were clothed and ate to their fill.

Sunan Abi Dawud Book 15, Hadith 271 Next Hadith → The Messenger of Allah (ﷺ) used to give a quarter of the booty as reward after the fifty had been kept off, and a third after the fifth had been kept off when he returned.
