Is the entire amount of 31,800 Dinars obtained from the shares of a usurious bank lawful, or only 30,0 Dinars (the current capital without the profits)? What is the ruling on the free shares that the bank will give? Does the ruling differ if the value of the shares has not yet reached the original capital?

Before answering, we caution that one who deals in usury is at war with Allah. It is obligatory for you, after possessing the money, to dispose of the shares of the usurious institution. What you inherited from your father, amounting to 30,0 dinars, is solely your right. As for any amount exceeding that, it is usurious gain that you are not permitted to keep. You must dispose of it for charitable purposes, and it is not permissible to use it to compensate for the decrease in the value of the shares.
