The ban has been enforced under the Unlawful Activities (Prevention) Act (UAPA) and approved at a meeting of the Union Cabinet.

The law defines ‘unlawful association’ as any organisation “which has for its object any activity that is punishable under Section 153A or 153B of IPC” – provisions dealing with threat to social and communal harmony.

Declaration of IRF as ‘unlawful’ under Section 3 of the UAPA will force closure of its offices and interests across the country.

According to sources in the home ministry, there was a solid case for proscribing IRF based on inputs and material shared by the Maharashtra government and the central intelligence agencies.

There are FIRs against Naik and other IRF members under Section 153A and 153B of IPC in 2 police stations of Mumbai, 1 in Kerala and two in Sindhudurg. There are several of Naik’s speeches compiled by Intelligence Bureau (IB) including where he extolls Osama bin Laden, claiming that 80% of Indians had not been Hindus as Muslims could have converted them “if we wanted” by sword, justifies suicide bombings, claims Golden Temple may not be sacred as Mecca and makes objectionable comments against Hindu gods. Most of these speeches form the content on Peace TV, a part of which was put together by Mumbai-based Harmony Media Pvt Ltd that once had Naik and his wife as directors. Large money transfers have been detected from UK-based charity IRF International, run by Naik to Harmony Media.

As per the Cabinet note proposing action against IRF, which incorporated legal opinion favouring a ban on the NGO for disturbing communal harmony and attempting forced conversions, Zakir Naik has been promoting enmity between religious groups and inspiring Muslim youth in India and abroad to commit terrorist acts.

The NIA is also examining the option of slapping terror charges against Naik, based on testimonies of around 50 terror accused and convicts lodged in various jails, stating that they were motivated by his speeches to take up jihad.

Naik came under the scanner of the security agencies after Bangladeshi newspaper ‘Daily Star’ reported that one of the perpetrators of the July 1 terror attack in Dhaka, Rohan Imtiaz, ran propaganda on Facebook last year quoting Naik.

The Islamic orator is banned in the UK and Canada for his hate speech aimed against other religions. He is among 16 banned Islamic scholars in Malaysia.

He had been popular in Bangladesh through his Peace TV, although his preachings often demean other religions and even other Muslim sects. The Mumbai-based preacher has not returned to India ever since the controversy erupted.
