He says, I want to buy a device from a country, and in this country I can't buy it with cash.

Meaning, I can't buy this device with cash, I have to buy it in installments, and that's how they do it, installments, and if I delay, they add an extra amount. I don't intend to delay, right? That's from me.

Okay, and he doesn't intend to delay, and he can't find this device with anyone else.

Yes, there is no problem inshaAllah the Exalted if he intends not to delay, but.

The basic rule is, if he finds it with someone else or can buy it with cash, no, he shouldn't enter into a contract that might involve riba.

No, no, no, it's not allowed. Yes, here.
