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 is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
In principle it is not permissible to abide by this regime, but if the government made it compulsory, then it is permissible to abide by it due to necessity. However, when receiving the money along with the interests at the end of the service, one has to get rid of these interests by spending it in charitable fields, like giving it to a needy relative whom one is not obliged to spend on. So it is not permissible for a person to benefit from the interests of his own wealth, but the destitute, poor and needy people could benefit from it.
Allaah knows best.
