What is the ruling of Islamic law regarding how to determine the percentage of partners' contributions in a residential construction project, taking into account the fluctuation of dollar and gold exchange rates, the variation in transferred amounts, and one partner selling an apartment at a price below market value?

All amounts were in Syrian Lira upon receipt, whether from inside Syria or outside it, and their value in other currencies or gold is irrelevant.

As for the partner who mediated the sale of an apartment, he is not responsible for the price difference if the apartment owner agreed to the reduction. And calculating the contribution in dollars is not applicable, as all contributions were in Lira.

We warn that injustice and betrayal in a partnership remove its blessing, as Allah Almighty says: "I am the third of the two partners as long as one of them does not betray his companion. If he betrays him, I depart from between them."
