The Ruling on Selling Checks for a Profit at Service Offices

Question:
My brother, Honorable Shaykh, may Allah grant you success. I work in the passport office. Currently, there are checks used instead of cash for residency permits, transferring sponsorship, and other matters. There are service offices that sell these checks and take a profit from the citizen. The citizen buys these checks from the service offices for a higher price instead of from the bank, because the bank is crowded. Is this permissible?

Answer:
It is not permissible to sell, O Shaykh. Selling a check is selling a document containing the amount. It is not permissible to sell them, because you are selling dirhams for dirhams. You are selling dirhams that you will take for dirhams in the bank. You sold the check, but in reality you sold your dirhams in the bank for dirhams you take from this person. This is selling dirhams for dirhams, so this is not permissible. Selling dirhams for dirhams that are not present.
