What gimmick is this? Islam forbids taking interest on money LENT by Muslims, not paying interest on money BORROWED from others, as far as I know.
Nice, evil way for Muslims to be preferentially treated over others who have to pay interest to keep the banks working. Don't worry, the money lost to the Muslims will be pinched from the pockets of the "infidels".
Read it again. An independent corporation buys the house on behalf of the Muslims using a 30-year fixed-rate mortgage, and then leases it to them for 10 years. Their lease payments cover the cost of the interest on the mortgage, but they can tell themselves it's a rent-to-own situation.
Good God, there's no free lunch here. It's all spelled out in the article. Why do people believe that it would be any different? If Muslims decided their religion didn't let them pay taxes, the IRS would be on them like white on rice.
