Khums

It is obligatory in the religion of Shi’ism to pay 20% of the annual profits (Shi’a Muslim deduct all expenses and calculate 20% of the profits) to the Imam, or his representative, or the authority of imitation. The imam or imitation authority uses this amount to help the needy and revive religion. Thus the Imam or his representative does not need the financial support of the ruler and the kings. Therefore, religion is independent of the state.
