What is the ruling on purchasing foreign currency before the time for paying the amount to the owner of the imported goods arrives, in anticipation of expected harm?

The questioner : In another form of the same issue.

The Shaykh : Yes.

The questioner : ... a little, meaning, let us suppose that I sold goods to Zayhir on credit, and I am to import them for him. Their value today in foreign currency is ten thousand. To ensure that I remain at the same price—for example—I calculated that when I returned, the price of the pound sterling was, for example, half a dinar. So I went and bought this currency and kept it with me; so that when the payment becomes due after a few months, I will have neither lost nor gained. I calculated that I am aware of its value today, so this is not trading. And although I bought it in advance, it is permissible when I pay the money...

The Shaykh : Here it is completely different from the cases we were discussing... On the contrary, this is a precaution to avoid falling into a problem that violates the Shari'ah.
