Are cards with a specific expiration date, such as communication cards, considered gharar (excessive uncertainty in a contract)?

The questioner:
May Allah reward you, Your Eminence, father. The questioner says: What is your opinion regarding cards that have a specific time limit for use, which may expire before they are used, such as some communication and internet cards? Do these cards fall under the issue of gharar (excessive uncertainty in a contract)?

The Shaykh:
And what is the question?

The questioner:
He says: What is your opinion regarding cards that have a specific time limit for use, which may expire before they are used, such as some communication and internet cards? Do these cards fall under the issue of gharar (excessive uncertainty in a contract)?

The Shaykh:
And Allah, transactions have occurred, transactions and tricks and things and deceiving people and eating the money of people, including this work. It is supposed that if a person buys the card, he uses it until it is exhausted, and no time is set for it, no time is set for it. As long as it is valid for use, it is used, because he paid its price. So he uses it until it ends without a time limit. Yes.
