Is Al Baraka Bank considered usurious after purchasing government debt instruments, and if so, is it permissible to dispose of thirty percent of the profits generated therefrom?

"Government religious tools" are usurious loans, and it is forbidden to deal with them. If the bank deals with usury, you must withdraw your money from the investment account and put it in the current account for safekeeping only, except in cases of extreme necessity, while avoiding interest. There are other Sharia (definition) problems in this bank's transactions. Strive to deal with another bank that is more committed to Sharia guidelines. If you are outside your country and cannot withdraw your balance, transfer it to a current account instead of a savings account, or leave the situation as it is until you can withdraw it upon your return. As for previous profits, give out half of them to purify the money from forbidden interest.
