Irtidad is an open rending from within of the fabric of Muslim society which is responsible for repairing it immediately, just as it must repair and counter the harm of depravity. As defined by the Prophet — Allah bless and greet him — irtidad is a declaration of war against Muslim society from inside it. This is confirmed by the fact that irtidad is a public act bearing on all of one’s social and private contracts, not a private exploration conducted in a philosophical vacuum.
And only Allah knows best.
