They are the followers of Waasil bin Ataa’, who withdrew (‘Itizaal) from the gathering of Al-Hasan Al-Basree. He determined that the sinner is in a level between two levels. Thus, he is neither a believer nor a disbeliever, yet he will reside eternally in the Hellfire. ‘Amr bin ‘Ubaid followed him in that and their views concerning the Attributes of Allaah are based on ta’teel, like the Jahmiyyah, and concerning Al-Qadar, like that of the Qadariyyah.
They reject the relation of the Qadaa and the Qadar of Allaah to the actions of the servant. In regards to the one who commits a major sin, they hold that he will remain in the Hellfire forever and that he is extracted from the fold of Eemaan into a level between the two levels of belief and disbelief. Thus they oppose the views of the Jahmiyyah in regards to these two principles.
