Al-Anfal 8:41

WaAAlamoo annama ghanimtummin shay-in faanna lillahi khumusahu walirrasooliwalithee alqurba walyatama walmasakeeniwabni assabeeli in kuntum amantum billahiwama anzalna AAala AAabdina yawmaalfurqani yawma iltaqa aljamAAani wallahuAAala kulli shay-in qadeer

And know that anything you obtain of war booty - then indeed, for Allāh is one fifth of it and for the Messenger and for [his] near relatives and the orphans, the needy, and the [stranded] traveler, if you have believed in Allāh and in that which We sent down to Our Servant on the day of criterion [i.e., decisive encounter] - the day when the two armies met [at Badr]. And Allāh, over all things, is competent.

And know that whatever spoils you receive, its one fifth is for Allah and for His Messenger, and for kinsmen and orphans and the needy and the wayfarer, if you do believe in Allah and in what We have sent down upon Our Servant on the decisive day, the day when the two forces encountered each other. And Allah is powerful over everything.
