This document is a rebuttal of a research paper that tried to justify the practice of Riba (usury) in Islamic finance. The rebuttal argues that Riba is clearly prohibited in the Quran and Sunnah and that financial institutions can thrive without it. The Muslim economy does not need Riba and will flourish if it implements Sharia law as prescribed by Allah. Comparing Haram (prohibited) practices to Halal (permissible) ones to justify the Haram is not allowed.
