The Council of Senior Muslim Scholars released their statement on Twitter saying:

The bombings that targeted two churches in Egypt are criminal acts and forbidden by Islamic law. Muslims are in agreement that these acts are a violation to the security, stability and safety of people.

A Muslim who believes in God and the Last Day will not commit such crimes. These crimes are committed by those who deviate from their faith.

These acts are forbidden in Islam for they are acts of treachery, betrayal, sin and aggression.
