After the death of Umar in 644 Aisha's proto-Karaites fell under the rule of a Karaite convert to the Judeo-Baptist Gnostic Faith called Uthman who was opposed by other proto-Karaites. Uthman wanted to stop the spread of Judeo-Baptist Gnostic material in common Quraysh Arabic and tried to include many Karaite ideas. He also tried to win support from Pope Martin of Gaza. But his attempts were ultimately unsuccessful. Yazdegard III attempted an unsuccessful uprising against Uthman before fleeing with his Nestorian sons to Central Asia where he was given a Christian burial.
