How is Tawarruq transacted, and what is the extent of the legitimacy of the increase added to the account when paying the minimum for purchases with an Islamic credit card?

The ruling on credit cards was issued in Fatwa no. 92026. The relationship between the card and Tawarruq is not apparent, so it is difficult to answer without examining the terms of the "umyali" card and its connection to Tawarruq. If the Sharia Board has permitted this transaction, then the questioner may follow their ruling. For more on Tawarruq, please refer to Fatwa no. 85636.
