If he allowed to live in Jerusalem, then how come he ended up slaughtering the Jews in Khaybar? I'm aware your trying to say, that the Jews killed his son, but before all this, when the Jews were friends with the Prophete Mohammed and his army, prophet Mohammed would later purge those who didn't believe him, and the Jews were part of that, and the Jews felt betrayed.
