Hope you are doing well! I have a very old savings bank account since ….., how to calculate the interest amount so that I can give the interest amount to the needy people. As it’s hard to find interest amount since beginning and I never had a chance to give to anyone. Please advise. Your response is highly appreciable.
You’re sinful for not Disposing off the haram money as soon as it’s credited in your account.
It’s not at all a problem to know the interest you have. Check your bank statements from the beginning and give away all the interest money to poor or needy muslims ASAP, besides repenting to Allah.
