The reason for the prohibition of prepaid phone cards

Question:
May Allah reward you, Honorable Shaykh. This questioner says: You have mentioned the prohibition of the prepaid phone card known as Sawaa. If this is established from you, what is the reason for the prohibition?

Answer:
Yes. I say that it is not permissible because it is time-limited. If the period passes and you have not used it, it is lost and your money is gone. This falls under the category of a lease. They leased you the phone to use. And a lease is not time-limited.
A lease is not time-limited. The lease that is time-limited is a lease on the item itself, but a lease on the use is not time-limited. So they took your money, and you are entitled to benefit from it until you exhaust this lease. By what right do they consume your money?
A general lease does not combine a specific duration with the lease; rather, it is open-ended. So if you came to a washer and gave him my clothes, with the garment costing one riyal, and said to him, "On the condition that you wash it within three days, or iron it within three days," and if he washed it after three days, you would have no claim. This is invalid; this is invalid. A general lease is not time-limited. Yes, a specific worker is the one who is time-limited; he works for you for a day or two to build for you. But a general worker, one who sits and sews clothes or washes clothes, his duration is not time-limited. Yes, because what is required is only the work. Yes.
