Agency in Interest-Based Wealth

Question: I have a brother who has accounts in interest-based banks in Egypt. He has granted me power of attorney over his bank accounts, which consist of deposits with annual interest, and asked me to withdraw the deposits and draw from his account to purchase lands that he owns. Will I be sharing in his sin, or am I merely executing a service for my brother? Please inform us. May Allah reward you with good.

Answer: There is no harm in executing what your brother has authorized you to do regarding the principal of his wealth. As for the interest, it is riba (usury or interest), and it is not permissible for you to execute it in his interests. Rather, dispose of it in the interests of Muslims, or in charity for the poor, because it is a corrupt gain. May Allah guide everyone to what pleases Him.
