Buhlål the Ruler of Rey in the Time of H§rån al-RashÊd:A Study Based on a Coin Minted in MuhammadÊya (173 AH)

This article raises the question of who is meant by Buhlål inscribed on the coin of Ray multiplied in 173 and whether it is the name or title of a person or a phrase in confirming the grade and quality of the coin. In order to obtain the answer of MuhammadÊya mint coins in the years 170 to 173 AH were compared with the data of written sources. According to the findings of this study, the Buhlål engraved on the MuhammadÊya coin is the famous Buhlål of the Abb§sÊd era, namely Abū wuhayb b. ʿAmr b. Moḡīra. With the BarmakÊds domination in the Harån period, Yahy§ BarmakÊ sent Buhlål as the MuhammadÊya (Ray) administration. Buhlål  did  not be in this office for a long time because of his tendency towards Shiism and possibly the caliph's concerns. Then he pretended to be mad and spent the last years of his life in Kåfa.
