Q: I am renting out a property which is currently on an unlawful mortgage. Is the income/profit made from this property therefore unlawful too?
الجواب حامدا ومصليا ومسلما ومنه الصدق والصواب
A: Whilst it is unlawful to take out an interest-based mortgage the mortgage funds themselves are not unlawful. It is the interest one pays or agrees to pay that is unlawful. Thus, the reprehensibility of the mortgage does not transfer to the property purchased therewith and any income/profit earned is lawful.
