Are investment deposits in banks considered usury or gambling?

Deposits in Islamic banks that adhere to Sharia controls and whose investments are permissible are lawful, and their profits are halal. As for usurious banks, or those that do not adhere to Sharia controls and invest in usurious transactions or prohibited activities, it is not permissible to deposit money in them for interest. Their interest is considered usury, and they may combine usury and gambling, such as investment certificates with prizes.
