What did the Prophet Muhammad (saw) say about Jews and Muslims fighting each other?
 Narrated `Abdullah bin `Umar:                     Allah's Apostle said, "You (i.e. Muslims) will fight wi the Jews till some of them will hide behind stones. The stones will (betray them) saying, 'O `Abdullah (i.e. slave of Allah)! There is a Jew hiding behind me; so kill him.' "
