I read an article recently which was discussing Islamic mortgages.
It noted that Islam forbids charging interest so the mortgages are structured so as not to charge interest.
It also noted that it’s hard to get a Muslim mortgage in America because so few financial institutions offer them.
The lenders in Muslim mortgages make a profit. They just don’t call it “interest.” Depending on how the loan is structured, it is called “rent” or “profit,” which in either case is fixed into the purchase price and prorated over the term of the loan. A cynic might say that this is a distinction without a difference, but don’t say that too loudly or the Muslims might saw your head off.
