Investment funds in banks

A: Invest your money legally in methods other than banks, because the transactions of the banks are based on Riba (usury/interest). Thus, they are not truthful in saying that they invest their money legally, because what counts is what they do in most of their transactions. Thus, you should not trust them. Moreover, dealing with usurious banks implies encouraging and helping them to continue in their prohibited transactions. This is included in the prevention mentioned in what Allah (Exalted be He) says: ...but do not help one another in sin and transgression. And fear Allâh. Verily, Allâh is Severe in punishment. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
