The Messenger of Allah (s) said during his lifetime: “Whoever observes a ruler (sultan) legalizing what Allah has made unlawful, violating the covenant of Allah, opposing the Sunnah of the Messenger of Allah, and treating the creation of Allah sinfully and oppressively, and does not oppose him with his speech and action, Allah has a right to bring him to the same fate as that of the tyrant’s” (narrated by Imam Husain (AS), attributed in ‘Allama Majlis, Bihar al-Anwar, v. 44, p.381)
