He kindled a fire...
He kindled a fire, whose flames reduced to ashes seventy brave soldiers of Islam including Hamzah, and caused the blood of the righteous persons to flow in the land of Uhud. Men of Aws tribe decided to relieve the Muslims of the mischief of Ka'b. Two persons named Muhammad bin Maslamah and Abu Na'ilah arrived in his fortress in the guise of friends and blamed the Prophet and his religion.
They added that since the arrival of the Prophet in Yathrib all of them had been encircled by calamities and their persons and belongings had been destroyed. They enlarged on this topic so much that Ka'b felt that their views on the subject were identical with his. Then they said: "We have come now to purchase some grains from you and are obliged to pawn something, because we do not possess any cash at present".
Ka'b agreed to sell grains, but as regards the things to be given as security he uttered words which clearly displayed his base and impure spirit, for he said with utter shamelessness: "Your women and children should remain under my control by way of pledge". His remark disturbed the two persons so much that they said in reply: "Is it possible?" These two persons did not actually want to purchase grains. They came back to chalk out a plan to murder him.
They, therefore, made an offer at once to leave their weapons with him as security. Their object in making this offer was that when the armed persons approached his fortress he should imagine that they had come to leave their weapons with him as security and not that they had conspired against him. At night an armed group of the men of Aws gathered round his fortress, ostensibly with the purpose of purchasing grains. Muhammad bin Maslamah, who was Ka'b's foster-brother, called him.
Ka'b's wife objected to his going out in the darkness of night, but in view of the conversation which Ka'b had already had with them he came out of the fortress with perfect confidence and did not entertain any doubt on account of their being armed. Having encircled him they proceeded to a valley as if to show the commodity or to take possession of it. They had not yet gone far from the fortress when the men of Aws suddenly fell upon him and cut him to pieces.
In this way a dangerous enemy, a mischievous spy and a dreadful element, whose most ardent desire had always been to inflict a blow upon the Muslims, was removed from their path.
