NEW DELHI: : National minorities commission chairperson, Ghayorul Hasan Rizvi on Wednesday appealed that all those who were present at the Tablighi Jamaat congregation at their headquarters in Nizamuddin earlier in March in Delhi and left for their states must come forward, self - declare and get themselves tested for Coronavirus to prevent its spread.While assuring that those who come forward to self -declare their presence at the congregation need not fear, Rizvi warned that those who do not come forward should be ready to face action as it is about the health and safety of so many others.To ensure there is no let-up on ground, Rizvi has written letters to religious leaders of all minority communities - Muslims, Sikhs, Christians, Buddhist, Jain and Zoroastrians to ensure strict enforcement of lock down norms in all religious places and educational institutions run by them like the madrasas and hostels. Letters have also been sent to the chief secretaries and DGPs of states and union territories."As we all know the Covid-19 has seriously affected the world and government of India, is taking every possible measure to combat and limit the effect of this pandemic. To contain the spread of this disease, 21 day lock down is in force. All the activities, except essential services, have been suspended and people have been asked to remain indoors," Rizvi states in his letter to religious leaders."To further this cause, Friday Namaz and other religious congregations of all the religions have already been stopped in all the religious places in the country which is appreciable. But the incident of Nizamuddin (Delhi) where a Jamaat was organised has done big damage to the efforts of the government to contain this virus. This amounts to a serious violation of the lock down and advisory to not hold any congregation at any religious place or education institution. This has put the lives of fellow citizens at risk," he added.The NCM chief has asked the religious leaders to advise their community members to assist in enforcing the lock down in all the religious places and educational institutions and prevent any gathering, if any, in such places. "People should be made aware of this emergent situation and respect the lock down," Rizvi asserted.
