Shar’ee solution to medical aid schemes
Q: Based on the Sharee solution at the end of this answer: https://muftionline.co.za/node/30854 , if the money is paid to the hospital or doctor directly monthly, and after one or two months, a service needs to be rendered that exceeds the amount the customer/patient has paid the doctor or hospital to-date, will that also be regarded as interest, or will it be acceptable due to it being a service received and not money?
