The sum which will be paid by the union to the bank is a loan given on behalf of the certified nurse as a down payment conditioned by the bank. This act is permissible in Sharia and the union`s administration is rewarded for it, provided that no increase on the loan`s value is stipulated upon settlement because the increase is from Riba (usury). Allah, The Almighty, Says in this regard (What means): “But if ye turn back, ye shall have your capital sums: Deal not unjustly, and ye shall not be dealt with unjustly.” {Al-Baqarah/279}. And Allah knows best.
