Al-Nadawi himself is the leader of the extremist organization in India and the spiritual father of the organization's branches in South Asia. He has previously supported the terrorist organization of Dae'sh and has publicly incited the killing of foreigners and the shedding of their blood.
Al-Nadawi, Al-Qaradawi's student, said in an extremist seminar , "If you are in a position to kill an American or a European, whether a Frenchman, an Australian, a Canadian or a Hindu, those who have declared war on Dae'sh, do it ".
Two days after the bloody incident, the Sri Lankan authorities announced they had been warned a few days before the incident that there are some moves by terrorist group planning a bloody attack through support from an international terrorist network.
Jama'at al-Tawhid in Sri Lanka followed the steps taken by the Muslim Brotherhood to take the umbrella of advocacy and charitable work in order to support and fund extremist thought and terrorist operations.
The group defines itself with caring of Muslim affairs in Sri Lanka, where Muslims account for less than 10 percent of its population. In 2016, the Sri Lankan government arrested the secretary-general of the Sri Lankan Tawhid for inciting against Buddhists, but he apologized for the incitement.
In 2017, the group returned to extremism and spread hatred again. The Sri Lankan government tried a number of the group leaders on charges of ridiculing Buddhist statues and hurting the feelings of Buddhist society.
Months before the terrorist attack, the group was also accused of vandalizing Buddhist temples and threatening the local population.
