The Qawmi madrasa-based organisation, which unleashed large-scale violence from its 2013 rally in Dhaka's Motijheel, issued the warning on Friday, two days before the High Court is scheduled to start hearing the appeal.
The radical outfit's Secretary General Junaid Babu Nagari said in a rally on the premises of Andarkilla Shahi Jam-e-Masjid in Chittagong that the organisation would announce 'tough programmes' if Islam was not to be retained as the state religion in the Constitution.
An amendment made in June 1988 during the tenure of military dictator HM Ershad inserted Article 2A in the Constitution, which gave Islam the status of state religion.
Fifteen eminent persons filed a writ petition the same year challenging the Eighth Amendment to the Constitution.
Of them, only Duttta, Umar, Jahangir, Serajul Islam and Anisuzzaman are alive.
