[Dr. Debate]

I've been reading about this and it confuses me. This meaning the "Massace of Banu Qurayzah", the Jewish Tribe in Medina. What do Muslims here have to say about this?

For all that don't know, people say that Banu Qurayzah was a tribe that was massacred by Prophet Muhammed's (PBUH) people back when he was alive.

Thanks.
