Roman Baths in 7th Century
Roman Thermae at Hamat Gader, under Israeli control a few kilometers from the Jordanian border. These Springs were restored and reopened in 663 AD by Mu'awiya I, who spared no expense in restoring the baths.
"The combination of a sacred spring, therapeutic thermae and a cultic theatre offered visitors the same type of religious, medical and social facilities which were available at many cultic centres throughout the Roman Empire."

This inscription is the only inscription to attest to the rule of Mu'awiya I in Syria. Mu'awiya I (661-680 AD) was the founder and first caliph of the Umayyad Caliphate ٱلْخِلَافَة ٱلْأُمَوِيَّة (651-750 AD), the second of four major caliphates after the death of Muhammad.
"In the days of Abd Allah ("Servant of God") Mu'awiya, the commander of the faithful, the hot baths of the people there were saved and rebuilt by Abd Allah son of Abuasemos (Abu Hashem?) the Counsellor, on the fifth of the month of December, the second day of the 6th year of the indiction, in the year 726 of the colony, according to the Arabs the 42nd year, for the healing of the sick, under the care of Joannes, the official of Gadara". The years quoted correspond to the year ca. 663 AD.
And this is a coin from the time of Mu'awiya I that imitated a Khusro drachm.
