After paying the 20% khums tax, the remaining 80% of the booty seized, spoils of war and treasure found was distributed among the commanders and soldiers as a reward for their effort, participating in the raid, or going to war against non-Muslims. The origins of the khums, states Abdulaziz Sachedina, go back to "the pre-Islamic Arab custom wherein the chief was entitled to one fifth of the ghanima (booty) in addition to the "safw al-ndl" (the portion of the booty which especially attracted him). The remainder of the booty was normally divided among the raiders who had accompanied the chief, but the latter reserved the right to dispose of the ghanima as he chose".
