Ḥaywah

Raja ibn Haywa was born circa 660 CE in Beisan (Beit She'an) and belonged to the Kindite tribe, possibly as a mawla or of actual Kindite descent. He served as a theological and political adviser to several Umayyad caliphs, including Abd al-Malik, al-Walid I, Sulayman, and Umar. Raja played a key role in overseeing the financing and possibly the conceptual design of the Dome of the Rock in Jerusalem. He was a mentor and chief secretary to Caliph Sulayman and influenced the succession of Umar over other Umayyad contenders. Raja was also known as a knowledgeable jurist and transmitter of traditions from companions of the Prophet Muhammad. He spent his final years in retirement but maintained contact with Caliph Hisham. His father was Haywa ibn Khanzal.
