It has been narrated on the authority of'Abdullah bin 'Umar that the Messenger of Allah ( صلی اللہ علیہ وسلم ) used to give (from the spoils of war) to small troops sent on expeditions something more than the due share of each fighter in a large force. And Khums (one-fifth of the total spoils) was to be reserved (for Allah and His Apostle) ( صلی اللہ علیہ وسلم ) in all cases.
