Most scholars say an interest-based mortgage is haram because it involves riba, which the Quran forbids (2:275, 2:278). Some contemporary scholars and councils allowed it in non-Muslim countries when a person has no other way to get a home, treating it as a case of need. Others reject this. Look first for an interest-free alternative such as a Sharia-compliant home finance plan, and ask a scholar about your situation.
آنان كه ربا مىخورند، در قيامت چون كسانى از قبر برمىخيزند كه به افسون شيطان ديوانه شده باشند. و اين به كيفر آن است كه گفتند: ربا نيز چون معامله است. در حالى كه خدا معامله را حلال و ربا را حرام كرده است. هر كس كه موعظه خدا به او رسيد و از رباخوارى باز ايستاد، خدا از گناهان پيشين او درگذرد و كارش به خدا واگذار مىشود. و آنان كه بدان كار بازگردند، اهل جهنّمند و جاودانه در آن خواهند بود.
اى كسانى كه ايمان آوردهايد، از خدا بترسيد، و اگر ايمان آوردهايد، از ربا هر چه باقى مانده است رها كنيد.
