2-Surah Al-Baqarah ( The Cow ) 85
Then, you are those [same ones who are] killing one another and evicting a party of your people from their homes, cooperating against them in sin and aggression. And if they come to you as captives, you ransom them, although their eviction was forbidden to you. So do you believe in part of the Scripture and disbelieve in part? Then what is the recompense for those who do that among you except disgrace in worldly life; and on the Day of Resurrection they will be sent back to the severest of punishment. And Allah is not unaware of what you do.
ثُمَّ أَنتُمْ هَٰؤُلَاءِ تَقْتُلُونَ أَنفُسَكُمْ وَتُخْرِجُونَ فَرِيقًا مِّنكُم مِّن دِيَارِهِمْ تَظَاهَرُونَ عَلَيْهِم بِالْإِثْمِ وَالْعُدْوَانِ وَإِن يَأْتُوكُمْ أُسَارَىٰ تُفَادُوهُمْ وَهُوَ مُحَرَّمٌ عَلَيْكُمْ إِخْرَاجُهُمْ ۚ أَفَتُؤْمِنُونَ بِبَعْضِ الْكِتَابِ وَتَكْفُرُونَ بِبَعْضٍ ۚ فَمَا جَزَاءُ مَن يَفْعَلُ ذَٰلِكَ مِنكُمْ إِلَّا خِزْيٌ فِي الْحَيَاةِ الدُّنْيَا ۖ وَيَوْمَ الْقِيَامَةِ يُرَدُّونَ إِلَىٰ أَشَدِّ الْعَذَابِ ۗ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ
Quran's Tafhim ( explanation)
*92). Before the advent of the Prophet (peace be on him) the Jewish tribes who lived on the outskirts of Madina had concluded an alliance with the Arab tribes of Aws and Khazraj. When the Arab tribes fought against one another each Jewish tribe fought on the side of its allies, which led to fratricide and so to a flagrant violation of the Book of God. Moreover, when the war ended the captives were ransomed. This ransom was justified on the basis of scriptural arguments; they extolled the Word of God when it permitted the ransom of prisoners of war, but attached no significance at all to the same Word of God when it prohibited mutual feuding.
