What do Muslim scholars say about Rashad Khalifa? You surely know that he, in order to prove a certain miraculous theory in the Qur'an (number 19), removed two verses from it, that he and his followers refuse everything from Sunnah, and finally, that he claimed to be a messenger of GOD.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Whoever claims to be a Prophet or denies the authenticity of the Sunnah or denies a verse from the Quran is a non-Muslim and went out of the fold of Islam even though he claims to be a Muslim.

There is a consensus of all the scholars about this.

Allah knows best.
