Judaism's core literature comprises the first five 'books of Moses' (=Torah) in the holy bible's 'old testament'. In accordance with the Torah, mankind's Edenic 'original sin' is inescapable: Man can only suffer El's wrath and Commandments until El decides to send a 'redeeming' Messiah.

Christians and Muslims believe that this Messiah did arrive in the person of Jesus Christ and Mohammed respectively, but Judaism rejects both - the basics for the hopefully-redeemeds' hatred of the parent cult for snatching away their promise of posthumous Paradise instead of the hideous, eternal nightmare in the Jewish Sheol.

In the 13th century CE, however, Jews (and uncertain Christians) were offered a new hope for non-messianic redemption: the spanish jew Moses de Lyon authored a series of books, the Zohar ('splendor'), claiming to reveal divine mysteries concealed in the Torah. The mysticism contained in the Zohar is know as (hebrew) Cabala (/'Qabala' /'Kabbalah'/etc.)
The word means 'aligned' or 'corresponding', and purported to chart an initionary pathway to redemption by personal effort alone.

Moses de Lyon ascribing the Zohar to the 2nd-century rabbi Simon bar Yochai, who hid in a cave for thirteen years studying the Torah and was inspired by the prophet Elijah to write the Zohar. *Leon's wife confessed that her husband had written it, using the prophet for profit.

Muslims do not believe Muhammad is the Messiah. They believe Christ is the Messiah as well, but that Muhammad was a man who received divine inspiration as an 'update' since they believe Christianity had been corrupted from Christ's original message.

They aren't wrong about the last part, but Islam just ends up being an amalgam of Jewish, Christian Arian, and Arab pagan beliefs.
