Well, that’s your POV.
Muslims believe that Abraham was a Muslim prophet. :)
They don’t believe Islam began with Mo, he’s just the last and greatest of a long line of prophets. Besides Abraham, it includes Moses, Solomon and Jesus. Who’s #2 in rank after Mohammed, BTW.
The point I was making is the covenant between God and the Jews was the first...
Many cultures and peoples copied them...
Many Jews fell away from the faith or intermarried with non-Jews. and keep their customs...
The old testemant is filled with stories of the Jews turning away from their faith and intermarriging with pagan religions...
