Relations with the Jews
                    Before the advent of Islam, 
                      the Jews were well established in and around Madinah. Their 
                      chief tribes, the Banu Nadhir, Banu Qainuqa and Banu Quraizah, 
                      lived in well-fortified areas. They controlled the economy 
                      of Madinah and owned practically all the date groves. They 
                      were money-lenders who charged enormous interest in their 
                      financial dealings. This allowed them to establish an extensive 
                      sphere of influence over the poor and illiterate Arab tribes 
                      of Aus and Khazraj. Even the wives and children of people 
                      were pawned and mortgaged to them as securities against 
                      non-payment. In addition to their political and economic 
                      domination they were also known for their religious knowledge 
                      of the scriptures. On the arrival of the Prophet Sallallahu 
                      Alaihi Wasallam in Madinah, most of the people of Aus and 
                      Khazraj embraced Islam and the Jewish stronghold over them 
                      diminished. 
                    As time passed the Jews began 
                      to plot against the Prophet Sallallahu Alaihi Wasallam. 
                      No kindness or generosity on the part of the Prophet Sallallahu 
                      Alaihi Wasallam would satisfy them. They soon broke off 
                      the treaty made by the Prophet Sallallahu Alaihi Wasallam 
                      and began conspiring with the enemies of Islam. They slandered 
                      the Prophet Sallallahu Alaihi Wasallam, twisted their tongues 
                      and mispronounced the Qur’anic words. They used to 
                      greet him with the words : "Assaamu Alaikum" 
                      (May death overtake you), instead of "Assalaaamu 
                      Alaikum" (May peace be upon you).The Jewish poets 
                      insulted all sense of common decency and began to ridicule 
                      Muslim women in obscene verses.
                    The Jews tried to sow the seeds 
                      of animosity amongst the people of Madinah. By their superior 
                      education, intelligence and their friendship with the hypocrites 
                      they now arose as a most dangerous element within the city. 
                      They had previously also played a role in inciting the Quraish 
                      to avenge their defeat at Badr.
                    Examples of their troublesome 
                      nature were many and open. The Jewish tribe of Banu Qainuqa 
                      were goldsmiths by trade. They were always arrogant and 
                      haughty. Once a Muslim woman had gone into their market 
                      to sell milk when some Jews insulted and humiliated her. 
                      A Muslim went to her rescue but the Jews killed him. 
                    On another occasion a Jew by 
                      the name of Shas Ibn Qais created a major tumult amongst 
                      the Aus and Khazraj when he reminded them of the Bu'ath 
                      war that they had previously fought between themselves. 
                      There would certainly have been bloodshed had the Prophet 
                      Sallallahu Alaihi Wasallam not intervened and reunited their 
                      hearts.
                    Another Jew by the name of 
                      Kab Ibn Ashraf was a leading figure in Arabia. His wealth 
                      allowed him to wield a high degree of influence amongst 
                      the Arabs and Jews. He hated Islam from the bottom of his 
                      heart. After the defeat of the Quraish at Badr he personally 
                      went to Makkah and offered condolences. Being a poet he 
                      often composed poems reviling the Prophet Sallallahu Alaihi 
                      Wasallam. Poetry was a powerful weapon amongst the Arabs 
                      and entire tribes could be ignited through the satirical 
                      words of the poets. Muhammad Ibn Maslamah Radhi Allahu Anhu 
                      finally killed Kab under the instruction of the Prophet 
                      Sallallahu Alaihi Wasallam. 
                    The Prophet Sallallahu Alaihi 
                      Wasallam realised that if this type of rebellion by the 
                      Jews was allowed to go unpunished Madinah would be turned 
                      into an arena of hostile factions, murder and chaos. It 
                      was necessary to put a stop to this with a firm hand or 
                      else peace and security would never prevail in Madinah.
                    The Prophet Sallallahu Alaihi 
                      Wasallam ordered the siege of their fortress in Madinah. 
                      After sixteen days the siege was lifted and the Jews surrendered 
                      and begged for mercy. Abdullah Ibn Ubay Ibn Sulool, the 
                      leader of the hypocrites, who was also a friend of the Jews 
                      pleaded with the Prophet Sallallahu Alaihi Wasallam to spare 
                      their lives. But, the Banu Qainuqa could not to be trusted 
                      anymore and the Prophet Sallallahu Alaihi Wasallam ordered 
                      their banishment from Madinah. They then settled at Khaibar.
                    The Banu Nadhir were also a 
                      treacherous tribe and were noted for their evil plotting 
                      against the Prophet Sallallahu Alaihi Wasallam. Once, while 
                      conversing with a few Sahabah, the Prophet Sallallahu Alaihi 
                      Wasallam was seated in the shade of a house when a Jew, 
                      Amr Ibn Muhasin, climbed stealthily onto the flat roof with 
                      the intention of crushing the Prophet Sallallahu Alaihi 
                      Wasallam with huge stones already placed there. By divine 
                      inspiration, the Prophet Sallallahu Alaihi Wasallam looked 
                      up just as he was about to throw down the stones. He moved 
                      quickly away and his life was saved.
                    The Banu Nadhir had now placed 
                      themselves in exactly the same position as the Banu Qainuqa 
                      had previously done. They had by their own act of deceit 
                      and treachery put themselves outside the pale of the treaty. 
                      The Prophet Sallallahu Alaihi Wasallam sent a message to 
                      them asking them to embrace Islam or to vacate Madinah. 
                      Relying on the support of Abdullah Ibn Ubay Ibn Sulool and 
                      with two thousand men to defend their settlement the Banu 
                      Nadhir returned a defiant answer. The Prophet Sallallahu 
                      Alaihi Wasallam set out to punish them. The Banu Nadhir 
                      shut themselves up in their strongholds and held out for 
                      ten days. They finally asked for peace and agreed to evacuate 
                      Madinah.
                    The Jewish lands and weapons 
                      that they could not carry away were distributed by the Prophet 
                      Sallallahu Alaihi Wasallam among the Muhajireen with the 
                      consent and cordial approval of the Ansaar. (1)
