Does the definition "postponing judgment on the perpetrator of a grave sin until the Day of Resurrection, so no worldly verdict is passed on him" apply to the Murji'ah, or is it the view of Ahlus-Sunnah wal-Jama'ah?

The reasons for naming the Murji'ah as such vary. It has been said that irja' means delay, and the Murji'ah delayed action from intention and belief. It has also been said that it means giving hope, as they claim that disobedience does not harm one's faith. Another opinion is that they delayed the judgment of the perpetrator of major sins until the Day of Judgment, or that they delayed Ali from the first rank in the caliphate. The correct view is that irja' is derived from delaying action and excluding it from the definition of faith, which is the meaning that became established in the usage of the Salaf and the Imams.
