Q: my mum is at an age wherein she gets discounts when she shows her identity card. I definitely do not qualify for such discounts. Can I use this card for discounts on my personal purchases. It gets me up to 25% off at certain grocery stores.
A: For you to use her nontransferable card for your personal shopping would not be permissible.
Alternatively, she can purchase it for you. You can compensate her. Kindly look at the agreement that is also attached with the usage of this card.
Allah Certainly Knows Best.
