John Fontain is a British Muslim apologist and debater, serving as a key member of the EF Dawah team. He is known for his composed and articulate style in engaging Christians and passersby at Speakers' Corner in Hyde Park, as well as in street dawah videos that contribute to the group's significant online viewership on platforms like YouTube. Fontain has participated in high-profile confrontations with figures like David Wood, positioning himself as a defender of Islamic theology against Christian apologetics. Beyond Speakers' Corner, he collaborates with prominent dawah practitioners such as Hashim and Mansur in broader outreach efforts, highlighting tensions in interfaith dialogues in public spaces in London. His activities draw both supporters and critics who accuse him of promoting divisive rhetoric. No formal education or professional background outside of dawah activism is publicly documented.
