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.
