Babak Khorramdin
Ali's son Sadaka II, better known as Zariq (Zardiq, Zuraiq, Zarir), ruled between 209 and 212 A.H. (824–827/8 A.D.) Like his grandfather (Sadaqa), Zariq was a capable warlord. He contacted Abbasids and claimed he is ready to battle Babak Khurramdin in return for his rule over Armenia and Azarbaijan. The Abbasid Caliph Al-Ma'mun accepted the deal and persuaded him to counter Babak Khorramdin who hid himself in the mountains of Azarbaijan.
