Asslamulaikum if we buy dollar and fix the rate and pay kwacha after 7 hours is permissible?
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In principle, if two different currencies are traded with one party trading on credit, then the currency will be traded on the market rate of exchange. Both parties cannot mutually agree on the exchange rate. In this instance, any amount over and above the market rate will be regarded as interest. For example, if Kwacha are exchanged for Dollars, the Kwacha will be paid after 7 hours on the current market rate of K18 to the Dollar.
A two sided credit transaction of currencies is not permissible. It is necessary for one party to take possession of his currency at the time of the transaction.
