Becoming a Member of an Organisation That Denies God and the Messenger

Question

Question: Can a Muslim be a member of, or otherwise take part in, an organisation (jama‘at) which denies God and the Messenger and calls every religion (dharma) the pastime of madmen?

Answer

If one who joins this organisation will have to become a denier of God and the Messenger, or will have to propagate their principles of unbelief and atheism, or will in practice have to commit acts of unbelief, then it is absolutely haram and impermissible for any Muslim to join this organisation.
