I am wondering if mortgage is viewed as halal, and if so what are the criteria. The sunni brothers and sisters claim that getting a loan on cars or getting student finance is permissible, as you know exactly how much you’re paying back at the end of the day, however with mortgage they claim that it’s haram as we are unaware how much interest we are paying each year, and the price of the house at the end of the mortgage. Please could you kindly explain to me the view the sistani marja’.
