The Twitter post that most riled the kingdom’s formidable conservative religious establishment and Ministry of Information was this one, written in Arabic: “Our Prophet had come to rectify the faith of Abraham, and now is a time when we need someone to rectify the faith of Muhammad.”

That is a shocking statement to those who believe the Prophet received Allah’s perfect and final revelation.

By suggesting the Saudi religious authorities are guilty of the very thing they believe they are defending against, and that this needs to be “rectified,” Hamad’s criticism was viewed as an assault on Islam itself and a direct challenge to state defenders of the faith.

On Monday Hamad was taken into custody by order of the Interior Ministry, Gulf News reported.
