All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu 'alayhi wa sallam, is His Slave and Messenger. Regarding the annual bonus given by the company to the employee as 'Workers Profit Participation Fund' (WPPF) and the like, then it is permissible for him to take it and benefit from it. It does not matter that a part of the company's profits comes from bank interest, because the company's money is mixed. So, it is permissible for the worker to take his right from its money and accept what it grants him of allowances, bonuses; and the unlawful percentage remains a part of the company's money, and not a part of what is taken by the workers, be it salaries or gifts. Allaah Knows best. (Source: islam_web) Classified in Fiqh of Transactions and Inheritance > Riba (Usury)
