Mohammad’s murders were not limited to camel thieves and individuals who opposed him.  A Jewish tribe called the Qurayza had been living in Medina when Mohammad relocated there.  They were resistant to converting to Islam.  There were accusations by Mohammad that the Qurayza were willing to form an alliance with the Meccans to fight against the Muslims.  However, before the Battle of the Trenches when the Meccans attempted to conquer Medina in 627, the Qurayza actually loaned the Muslims tools and weapons to help repel the attack.  The Qurayza did not get involved in the fighting when the Meccans mounted their siege of Medina.  The Meccans’ siege was unsuccessful and they withdrew after a relatively short time and with little actual fighting having occurred.  Obviously, there was no loot acquired by the Muslims after this battle.  Mohammad immediately turned his attention on the Qurayza who were the last of the three Jewish tribes remaining in Medina.  After a short siege, the Qurayza surrendered.  Mohammad had all the adult males of the tribe beheaded, one after another.  One Jewish woman who became hysterical during the all-day event was also murdered.  The property of the Qurayza became loot for Mohammad’s army and the women and children who had survived the massacre were enslaved.  Mohammad personally took the wife of one of the Qurayza leaders as a concubine and bedded her that very evening despite the fact he had executed her husband and son that day. 

The Battle of Khaybar is discussed elsewhere on this website, when discussing torture under Mohammad.  The Banu Nadir, who had first been exiled from medina by Mohammad were again assaulted at Khaybar.  This time they were soundly defeated and the adult males were murdered while the women and children were enslaved. These two genocidal massacres were both well documented in Islamic scripture.  They were not isolated events.  Instead they were typical of the violence and brutality of the Muslims under the direct leadership of Mohammad in his conquest of the Arabian Peninsula.  In neither case did the people that were massacred present a viable threat to the survival of the Muslims or to Mohammad.  To our mind, these events are clear evidence that Mohammad was not sent by the Creator to do these things.  Instead, they indicate that he was an ambitious, opportunistic and vicious conqueror who was not willing to let anything stand in the way of his objectives.
