And know that whatever you acquire on winning a victory, a fifth of it belongs to Allâh, to the Messenger and to the kindred and the orphan, and the needy and the wayfarer; (this you must observe) if you believe in Allâh and in what We sent down upon Our servant on the Day of Discrimination (between the truth and the falsehood), the day the two armies encountered each other (at the Battle of Badr). Indeed, Allâh is Possessor of power to do all He will.
