The sources consist of comments from viewers responding to a YouTube video by Khabib Nurmagomedov, a retired mixed martial artist, in which he criticizes the practice of riba (interest-based loans) and promotes an Islamic finance app called Wahed. Viewers express a range of opinions, with some agreeing with Nurmagomedov's stance on riba and others expressing skepticism about the app or criticizing his religious views. Some argue that the app, despite its halal claims, operates within the existing interest-based financial system and therefore contradicts Nurmagomedov's message. Others question whether the app provides a viable alternative to conventional banking, especially for those needing financial assistance. The comments also reflect varying perspectives on Islamic finance, the ethical implications of riba, and the challenges of navigating a global financial system built on interest.
