As to the cause of this and the following three verses, it is narrated that one of the Jews named SHAS-IBN-GHAIS who was a dark minded old devil, and much stubborn in his infidelity; passed by and saw a group of Muslims who held a meeting. They were of the two tribes of AWS and KHAZRAJ, known for their old and continuous enemity and hostilities; now sitting so friendly in a peaceful meeting with lovely discussion!

      If so the averse tribes go forward in friendship and peace, under the leadership of Mohammad thought the Jew; The Jewish accounts will soon be cleared, and the annihilation of our nation will be inevitable. The Jew then encouraged some interlocutor Jew, to attend that meeting and remind them of their bloody and dreadful battle of BOGHAS, in which many of the two parties tore and mutilated each other so that their old enmity might be renewed.

      The plot was not without effect, and the old enemies and new religious brothers began to wrangle with each other, and a quarrel was going to begin, when the prophet was informed and reached them in time. He made a very effective speech for them that opened their eyes once again. The parties laid their arms down, and washed out their old hatered and renewed their brotherhood.
