Q 2:
Is the profit of shareholders of a bank that deals in Riba (usury/ interests) also considered Riba?
A:
Yes, the profit of a shareholder in a usurious bank is also Riba. Moreover, it is considered eating up one another's property unjustly. Allah (Glorified and Exalted be He) says:
...whereas Allâh has permitted trading and forbidden Ribâ (usury).
It has been authentically reported that the Messenger of Allah (peace be upon him)
cursed the one who accepts Riba (usury), the one who gives it, those who witness it, and the one who writes it.
