So what were they before?? Sabbeans? Manicheans?

They were tribes of Arabs and were pagans. Mohammed introduced monotheism through the Q'uran. He was upset that the Jews wouldn't accept him as a prophet so he "bad-mouthed" them in the Q'uran.

I'm pretty sure that some of them belonged to another group and or groups, among them Sabbean and Manichean, and Osseans etc. The comment about not being accepted as a prophet by the Jews might be on the money though. And would explain some of the intense hatred the muslims have towards the Jews.
