Is it permissible to deposit or borrow money from Muslim banks whereby the interest is either received or paid out?
Answer
It is permissible to deposit money in a bank without prior condition for interest and it is as well permissible to take interest, if the bank in which money is deposited belongs to Muslims. If it belongs to government, it is permissible to take interest provided that half of the interest is given away to poor people (Momineen of them).
