Mahmoud Amer, the head of Egypt's religious group al-Sunna al-Mohamadiya, called on Egyptian opposition leader ElBaradei to "repent" for stoking civil unrest and opposing Egyptian President Hosni Mubarak, saying Egyptian rulers "have the right to kill (ElBaradei) if he does not desist."
Al-Sunna al-Mohamadiya, however, issued a statement saying that its primary mission is to uphold the teachings of the Islamic Prophet Mohammed.
"This fatwa contradicts the society's mission," al-Arabiya quoted the statement as saying. "We do not declare people apostates and we do not sanction the killing of anyone."
The group went on to say that the fatwa was a matter of Amer's "personal opinion," adding only statements made through official spokesmen could be attributed as credible positions.
The statement added that the message could tarnish the image of Islam, warning that it may take legal action against Amer.
Nevertheless, the group held to its belief that opposition to a ruler is forbidden.
"The society, however, has to make it clear that Islam prohibits rebellion against rulers," the statement read.
