Zakir Naik (born 18 October 1965 in Mumbai, India) is an Indian Islamic preacher, who has been called an "authority on comparative religion", "perhaps the most influential Salafi ideologue in India", and "the world's leading Salafi evangelist". He is the founder and president of the Islamic Research Foundation (IRF), and founder of the "comparative religion" Peace TV channel, through which he reaches a reported 100 million viewers.Unlike many Islamic preachers, his lectures are colloquial, given in English not Urdu or Arabic, and he wears a suit and tie rather than traditional garb.
Naik has held many debates and lectures around the world. Anthropologist Thomas Blom Hansen has written that Naik's style of memorising the Quran and Hadith literature in various languages, and his related missionary activity, has made him extremely popular in Muslim circles. Many of his debates are recorded and widely distributed in video and DVD media and online. His talks are usually recorded in English and broadcast on weekends on several cable networks in Mumbai's Muslim neighbourhoods, and on the Peace TV channel, which he co-produces. Topics he speaks on include: "Islam and Modern Science", "Islam and Christianity", and "Islam and secularism". Peace TV channel has been banned in India since 2012.
