Is it permissible to settle a dollar account at the rate recorded at the time of payment or at the new rate, knowing that the customs dollar rate is higher than the market rate?

The answer is summarized as follows:

1. Paid Brokerage: It is not permissible for your cousin to pay the price of the goods on your behalf if he is a paid broker, because this combines a loan and a compensation, which is forbidden according to the hadith: "A loan combined with a sale is not permissible." However, it is permissible if he brokers gratuitously.

2. Partnership: It is permissible for your cousin to pay the price of the goods, entirely or partially, if he is a partner.

3. Currency Exchange: Whether your cousin is a broker or a partner, he acts as your agent in exchanging currency and paying the price of the goods and customs.

If you give him money in Egyptian Pounds, the accounting should be in Pounds for the amount you paid, and the issue of exchange rate should not be mentioned.

If you give him money in US Dollars, the accounting should be in US Dollars. The amount can be paid in US Dollars or in Egyptian Pounds at the exchange rate on the day of accounting, so that the Egyptian Pounds paid can purchase the required US Dollars on that day. This also applies to a partner who pays in US Dollars.
