Is interest (riba) haram, including mortgages?

Riba is clearly forbidden in the Quran. Most scholars hold a conventional interest-bearing mortgage to be riba; a minority permitted one for a family home in need. Islamic home finance offers alternatives.

Yes. Riba, interest charged on a loan, is clearly forbidden in the Quran and is among the gravest sins in Islamic law.

Islamic home-finance contracts exist to avoid it.
