The Secrets of Rabbi Simon ben Yohai is a Jewish apocalypse composed in the mid-8th century, which presents itself as a record of the divine visions of the 2nd-century rabbi, Simon ben Yohai.
The visions described in the secrets portrays the Ishmaelite's being led by a violent saviour of the Jews from the hegemony of the Byzantine Empire.
[1] According to the text, Simon ben Yohai was hiding from the Roman emperor.
When Simon saw the Arab forces approaching, he expressed sadness, but was then immediately addressed by the angel Metatron:[1] Suspicious, Simon asks Metatron how he can know that the Arabs are God's salvation.
Nevertheless, the end of the prayer ultimately predicts that the Romans will take back Jerusalem.
