He believed there was no such thing as a low "reasonable rate of interest" and that even "the smallest and apparently harmless form" of interest was intolerable in Islam as rates would inevitably increased over time when the "capitalists" (moneylenders) squeezed the entrepreneurs (borrowers) eliminating any entrepreneurial profit. To replace interest-based finance he proposed "direct equity investment" (aka Profit and loss sharing), which he asserted would favor "societally profitable" ventures such as low-income housing that conventional finance ignores in favour of commercially profitable ones. To eliminate the charging of interest he proposed penal punishment with the death penalty for repeat offenders.
