...looks like they are trying to legitimize their activities by relating and comparing to Christ.
The only legitimacy to the Judeo/Christian scriptures is that God rebuked Israel for worshiping “Allah”.
Allah is the moon god that Israel backslided into.

They were not unknowing who Allah was when Mohammad chose him to create a monotheistic religion.
