I want to know about banking system as per Islamic Shariah. I am a Bangladeshi. There is many kinds of bank provided service. Some of them direct provided interest on deposit. Some of them paid indirect. Now I want to know if I deposit money in Bangladesh Islami bank then they provide me non fixed percentage on my deposit and if I deposit on fixed deposit scheme then they provided me a fixed percentage on my money. If I deposit money to other bank in Bangladesh they also provided same as I described. Islami bank said its a profit and other bank direct said its interest but they are following same policy. Now I want to know what is said about the banking in Islam. Can I take the profit from Islami bank or other bank on fixed deposit scheme and other scheme or not. I will be glad if you give me answer.
