Ali Dawah is a popular British Muslim YouTuber and dawah activist, prominent in the UK Muslim dawah community. He is known for frequently engaging in public debates at Speakers' Corner in Hyde Park, London, where he defends Islamic theology against Christian apologists, missionaries, atheists, and others. He co-founded the One Message Foundation (later rebranded or associated with Sapience Institute), which organizes dawah events and produces content aimed at countering perceived anti-Islamic narratives. His online presence extends across YouTube, Instagram, and TikTok, where he shares clips from debates and lectures, amassing a significant following among young Muslims. Dawah has been embroiled in numerous controversies, including public altercations and online disputes, such as a 2021 heated exchange at Speakers' Corner leading to police intervention. He has faced criticism for allegedly endorsing strict interpretations of Sharia and for statements perceived as inflammatory towards non-Muslims, with accusations of hypocrisy arising from leaked messages suggesting inconsistencies in his personal conduct versus public persona, though he denied them. Despite adversarial relationships with figures like David Wood, he maintains alliances with Mohammed Hijab and the High School Debate Club network.
