By Allah...

By Allah, it has come clear to you that he is a sent prophet and he is the very one you find in your Book, and thus you shall be safe in your bloods, properties, children, and women.” They altogether said, “We do never leave the judgment of the Torah and never replace it with any other than it.” Ka’b said, “If you deny this, then let us kill our children and women, and go out to Muhammad and his companions; only men with unsheathed swords leaving behind us nothing, until Allah will judge between us and Muhammad.

If we are killed, we are killed while leaving no progeny behind us that we may fear for them, and if we prevail, we, by my life, shall find women and children.” They denied this suggestion and said, “If we kill these poor ones, then what good is there in living after them?” Ka’b offered his third suggestion saying, “If you deny this too, then tonight is the night of Saturday, and Muhammad and his companions may give us security in this night.

So let us go down (of the forts) that we may find Muhammad and his companions in inadvertence.” They did not respond and they said to him, “(If we do) we shall corrupt our Saturday and do in it what those before us did not do except those whom you know and they were metamorphosed as it is clear to you.” [1] The delegation of Abu Lubabah The Banu Quraydhah asked the Prophet (a.s.) to send them Abu Lubabah, who was from al-Aws the allies of Banu Quraydhah, to consult with him on this affairs.

The Prophet (a.s.) sent Abu Lubabah to them, and when they saw him, they got up before him reverently and respectfully. Their women and children began crying in front of him. When he saw them in that case, he pitied them. They said to him, “What do you see, Abu Lubabah?

Do we submit to the judgment of Muhammad?” He said to them, “Yes, you do, (he pointed to his throat) but know well that his judgment on you is the slaughtering!” He suggested to them to resist and not to submit because he made them understand that the judgment would be the slaughter in any case. Then, Abu Lubabah regretted too much because he was certain that he had betrayed Allah and His messenger. He repented and Allah accepted his repentance.

[2] The arbitration of Sa’d The Banu Quraydhah sent for their ally the tribe of al-Aws to mediate between them and the Prophet (a.s.). A group from the al-Aws interceded with the Prophet (a.s.) who accepted the intercession and suggested to them to choose an arbitrator as they liked.
