Khums, in the Ja'fari Shia tradition, is applied to the business profit, or surplus, of a business income. It is payable at the beginning of the financial year, though this is regarded as being the time at which the amount becomes clear. "Ghanima" and one-fifth tax of khums applies wherever gain or profit is involved. "Ghanima" has two meanings as mentioned above; the second meaning is illustrated by the common use of the Islamic banking term "al-ghunm bil-ghurm" meaning "gains accompany liability for loss or risk"
