All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
One of the conditions for the validity of Mudhaarabah (profit sharing or co-partnership) is that the investor's profit is determined as a percentage of the overall profit, and it is not valid if the profit is a percentage of the capital money. So, if the agreement was a profit of 35% of your capital money, then this is a defective Mudhaarabah, and the profit resulting from a defective Mudhaarabah contract is for the owner of the capital money, and the worker (who carries out the Mudhaarabah) takes a fee of a worker who does similar work. But if it is clear that there is no real Mudhaarabah, then you are obliged to dispose of those profits by spending them on the general welfare of Muslims.
On the other hand, if the agreement was on a known percentage of the profit, and it was said that it may reach 35% of the capital money, then the contract is valid.
Anyway, since it has become evident that it was not a Mudhaarabah but rather a form of deception to consuming people’s money unjustly; then, in our view, you should dispose of it as we have already mentioned.
