The ruling on purchasing prepaid communication cards and paying for them in installments

Question:
May Allah reward you. The last question: The questioner says that some young men purchase a batch of prepaid communication cards, then they sell them to a person for a deferred price. Is this transaction permissible? And what is Your Eminence’s guidance on this?

Answer:
Is the prepaid card itself permissible or not? If it is permissible, is it permissible to sell it or not? I do not see the prepaid card as permissible, for it contains ambiguity, it involves loss, it contains doubt, and it has defects regarding money, such that when the time period passes, the value is lost on you, and you are a Muslim who paid its price. Why is it lost on you?
It is obligatory that when you receive its price, you do not use it until you have exhausted the value you paid for. As for setting a time limit after which your money is lost, this is a greater loss of money through invalidity. Yes, you bought it; if you buy a commodity, you take it and benefit from it until you have benefited from it. The place of purchase is where they want to buy a card; they buy it and sell it to him. Yes.
