One of their names for it is “murabaha” or cost-plus. They simply add a premium to the principal or sale price. It’s pre-paid interest. They’re fooling themselves by pretending they are not paying interest. It’s a form of self “taqiya”.
Cost-plus equals zero-coupon bond (on the interest). I guess Mohammed didn’t worry much about discounting calculations.
Next, Muslims will cry discrimination on the cost-plus.
Thanks! Learned something.
