 In the suburbs of Medina, there were Jew tribes. We have already mentioned about their treaty with the Muslims. And these tribes, they were not and ultimately they proved it that they were not trustworthy. According to the treaty that had been signed by Muslims and Jews, the Jews constantly violated it. And they violated those articles which demanded that they should be punished for that as it was mentioned in the treaty. Resultantly, when the sympathies of these tribes were seen and established with Quraish, then two tribes, one Banu Qiyanka and the other tribe, Banu Nuzer, they were expelled out of Medina. And now the treaty was no more effective for them or for the Muslims. And the Muslims also knew their intentions. They went outside Medina where they were dwelling and they made their own houses or the places to live when they were expelled out of Medina. Very clandestinely, down and under, they had shown complete sympathies to the Quraish of Mecca. And they got settled in the border areas of Khabar and Syria. Now just see, settling down in the border areas of Khabar and Syria is very meaningful. It's not simply that they had no other place. There were many other places and it was full open area and plain areas where they could settle. But by design, they settled in these areas and the design was that this was dominating that route which was used by the Quraish. Also, they were able to keep carrying out reconnaissance or general observation to get information. Who comes? Who goes? What are the people of Medina trying to plan? Are they coming this side? Are the forces coming this side? Are there people who want to get some information and collect some information for any future battle or any future war? They would be seen and ultimately they would inform the Quraish. They also on one side said to help them and on the other side and other conspiracy which they resorted towards to instigate the Quraish to attack Medina. Quraish were already full of revenge, full of those emotions which were against the Muslims. Obviously, their centuries-old prestige and privileges had been compromised, demolished or finished. So, that is why they were very keen to attack Medina and these Jews, they instigated them in various ways to attack Medina. They ensured also their complete help to the attacking force of Quraish. They committed it to the Quraish that whenever they attack Medina, Jews will be all out to support them in all possible manners.
