Михаил Сириец
Early Syriac sources use the terms "Hurdanaye, Kurdanaye, Kurdaye" to refer to the Kurds. According to Michael the Syrian, Hurdanaye separated from Tayaye Arabs and sought refuge with the Byzantine Emperor Theophilus. He also mentions the Persian troops who fought against Musa chief of Hurdanaye in the region of Qardu in 841. According to Barhebreaus, a king appeared to the Kurdanaye and they rebelled against the Arabs in 829. Michael the Syrian considered them as pagan, followers of mahdi and adepts of Magianism. Their mahdi called himself Christ and the Holy Ghost.
