In the case of the Ahmadiyya—who are accused by mainstream Sunni and Shia of denying the basic tenet of the Finality of Prophethood (Ahmadis state they believe Mirza Ghulam Ahmad is a mahdi and a messiah)—the Islamic Republic of Pakistan has declared in Ordinance XX of the Second Amendment to its Constitution, that Ahmadis are non-Muslims and deprived them of religious rights. Several large riots (1953 Lahore riots, 1974 Anti-Ahmadiyya riots) and a bombing (2010 Ahmadiyya mosques massacre) have killed hundreds of Ahmadis in that country. Whether this is unjust takfir or applying sharia to collective apostasy is disputed.
