Now, I am getting good offers from big Banks to work in their Foreign Exchange department. I will not be dealing with any interest in bank, I will not be connected to any interest involved transactions. Here also I only have to sale and purchase Foreign Currencies from travelers, my profit will be purely from profit earned through sell and purchase of foreign currencies (No Interest). I request you to please guide me (give Fatwa) whether I can work in Banks for Foreign Exchange.
بسم الله الرحمن الرحيم
If you have not to deal the interest based dealings in the bank where you want to work for Foreign Exchange and the owner of the bank is Muslim or it is an Islamic country and your salary will not be paid from the interest amount then you may work in the Foreign Exchange department of the bank. As the currency of two different countries are treated as separate kind and it is lawful to exchange them with difference with mutual consent provided one exchange is taken into custody in the meeting of transaction.
Allah knows Best!
