The Terms of the Covenant and their Breach of It

Allah criticized the Jews who lived in Al-Madinah during the time of the Messenger of Allah ﷺ. They used to suffer, because of the armed conflicts between the tribes of Al-Madinah, Aws and Khazraj. Before Islam, the Aws and Khazraj worshipped idols, and many battles took place between them. There were three Jewish tribes in Al-Madinah at that time, Banu Qaynuqa` and Banu An-Nadir, the allies of the Khazraj, and Banu Qurayzah, who used to be the allies of the Aws. When war erupted between Aws and Khazraj, their Jewish allies would assist them. The Jew would kill his Arab enemy, and sometimes they also killed Jews who were the allies of the other Arab tribe, although the Jews were prohibited from killing each other according to clear religious texts in their Books. They would also drive each other from their homes and loot whatever furniture and money they could. When the war ended, the victorious Jews would release the prisoners from the defeated party, according to the rulings of the Tawrah. This is why Allah said,

أَفَتُؤْمِنُونَ بِبَعْضِ الْكِتَـبِ وَتَكْفُرُونَ بِبَعْضٍ

This verse explains why the Jews will have to undergo such a severe punishment. They have been disobeying Allah in order to satisfy their desires and to enjoy worldly pleasures; they have also sacrificed for these things their salvation in the other world. Their sin being so great, Allah will not reduce or mollify their punishment, nor will He allow anyone to intercede on their behalf.
