‏Through this study, and in light of the evidence included in it, it has become necessary to know that the dirham of Caliph Harun al-Rasheed attributed to the Bisha mint; Preserved in the Qatar National Museum, it is a dirham bearing the name of the Baysh Mint.

‏This dirham, bearing the date of minting 186 AH, makes it, until the publication of this study, the oldest archaeological evidence in the field of Islamic coins bearing the name of the Baysh Mint, which makes it of great and immeasurable importance in the history of Islamic coins minted in the regions of the Kingdom of Saudi Arabia, and in the Jazan region in particular.
