So why are the Indian authorities not putting Naik behind bars? CDs (of Naik's incendiary videos justifying terrorism) have been found at Jihadi hideouts in India and abroad.
Britain bans controversial Indian preacher Zakir Naik
LONDON: Britain has banned controversial Indian Islamic televangelist Zakir Naik, who once claimed that "every Muslim should be a terrorist," from entering the country, citing his "unacceptable behaviour".
Home secretary Theresa May said 44-year-old Naik would not be allowed to enter the country under laws that can exclude anyone who writes or publishes material that can "foment, justify or glorify terrorist violence".
Indian television preacher Naik was due to give a series of lectures at arenas in Wembley and Sheffield.
May said the doctor was being excluded because repeated comments attributed to him was evidence of his "unacceptable behaviour".
She said: "Coming to the UK is a privilege not a right, and I am not willing to allow those who might not be conducive to the public good to enter the UK."
Website footage had shown the preacher making the claim that every Muslim should embrace terrorism.
Naik said Muslims should beware of people saying Osama bin Laden was right or wrong, adding: "If you ask my view, if given the truth, if he is fighting the enemies of Islam, I am for him.
If he is terrorising the terrorists, if he is terrorising America the terrorist, the biggest terrorist, every Muslim should be a terrorist."
He is also reported as saying that western women make themselves "more susceptible to rape" by wearing revealing clothing.
Mumbai-born Naik is a medical doctor by profession, having attained a Bachelor of Medicine and Surgery (MBBS) from the University of Mumbai.
Naik is the founder and president of the Islamic Research Foundation (IRF) which is a non-profit organisation. It also owns and broadcasts the free-to-air global Peace TV channel.
