The Prophet said, "Who is ready to kill Ka`b bin Ashraf (i.e. a Jew)." Muhammad bin Maslama replied, "Do you like me to kill him?" The Prophet replied in the affirmative. Muhammad bin Maslama said, "Then allow me to say what I like." The Prophet replied, "I do (i.e. allow you).

The Prophet said, "Who is ready to kill Ka`b bin Al-Ashraf who has really hurt Allah and His Apostle?" Muhammad bin Maslama said, "O Allah's Apostle! Do you like me to kill him?" He replied in the affirmative. So, Muhammad bin Maslama went to him (i.e. Ka`b) and said, "This person (i.e. the Prophet) has put us to task and asked us for charity." Ka`b replied, "By Allah, you will get tired of him." Muhammad said to him, "We have followed him, so we dislike to leave him till we see the end of his affair." Muhammad bin Maslama went on talking to him in this way till he got the chance to kill him.

"O Ka'b bin Murrah! Relate (something) to is from the Messenger of Allah (saws), and be cautious. He said: 'I heard the Prophet (saws) say: "Whoever develops some gray hair in Islam, it shall be a light from him on the Day of Judgement."

[Abu 'Eisa said:] There is something on this topic from Fadalah bin 'Ubaid and 'Abdullah bin 'Amr. The narration of Ka'b bin Murrah was reported like this from Al-A'mash, from 'Amr bin Murrah.

This Hadith is been reported from Mansur, from Salim bin Abu Al-Ja'd, and he included a man between him and between Ka'b bin Murrah in the chain. He is called: "Ka'b bin Murrah," and he is called: "Murrah bin Ka'b Al-Bahzi," and the one known among the Companions of the Prophet (saws) is Ka'b bin Murrah Al-Bahzi, he reported some Ahadith from the Prophet (saws).

Allah's Apostle said, "Who would kill Ka`b bin Al-Ashraf as he has harmed Allah and His Apostle ?" Muhammad bin Maslama (got up and) said, "I will kill him." So, Muhammad bin Maslama went to Ka`b and said, "I want a loan of one or two Wasqs of food grains." Ka`b said, "Mortgage your women to me." Muhammad bin Maslama said, "How can we mortgage our women, and you are the most handsome among the Arabs?" He said, "Then mortgage your sons to me." Muhammad said, "How can we mortgage our sons, as the people will abuse them for being mortgaged for one or two Wasqs of food grains? It is shameful for us. But we will mortgage our arms to you." So, Muhammad bin Maslama promised him that he would come to him next time. They (Muhammad bin Maslama and his companions came to him as promised and murdered him. Then they went to the Prophet and told him about it.

that he heard Allah's Apostle saying, "(Moses) said, 'Call me not to account for what I forget and be not hard upon me for my affair (with you)' (18.73) the first excuse of Moses was his forgetfulness."

Allah's Apostle said, "Who is willing to kill Ka`b bin Al-Ashraf who has hurt Allah and His Apostle?" Thereupon Muhammad bin Maslama got up saying, "O Allah's Apostle! Would you like that I kill him?" The Prophet said, "Yes," Muhammad bin Maslama said, "Then allow me to say a (false) thing (i.e. to deceive Ka`b). "The Prophet said, "You may say it." Then Muhammad bin Maslama went to Ka`b and said, "That man (i.e. Muhammad demands Sadaqa (i.e. Zakat) from us, and he has troubled us, and I have come to borrow something from you." On that, Ka`b said, "By Allah, you will get tired of him!" Muhammad bin Maslama said, "Now as we have followed him, we do not want to leave him unless and until we see how his end is going to be. Now we want you to lend us a camel load or two of food." (Some difference between narrators about a camel load or two.) Ka`b said, "Yes, (I will lend you), but you should mortgage something to me." Muhammad bin Mas-lama and his companion said, "What do you want?" Ka`b replied, "Mortgage your women to me." They said, "How can we mortgage our women to you and you are the most handsome of the 'Arabs?" Ka`b said, "Then mortgage your sons to me." They said, "How can we mortgage our sons to you? Later they would be abused by the people's saying that so-and-so has been mortgaged for a camel load of food. That would cause us great disgrace, but we will mortgage our arms to you." Muhammad bin Maslama and his companion promised Ka`b that Muhammad would return to him. He came to Ka`b at night along with Ka`b's foster brother, Abu Na'ila. Ka`b invited them to come into his fort, and then he went down to them. His wife asked him, "Where are you going at this time?" Ka`b replied, "None but Muhammad bin Maslama and my (foster) brother Abu Na'ila have come." His wife said, "I hear a voice as if dropping blood is from him, Ka`b said. "They are none but my brother Muhammad bin Maslama and my foster brother Abu Naila. A generous man should respond to a call at night even if invited to be killed." Muhammad bin Maslama went with two men. (Some narrators mention the men as 'Abu bin Jabr. Al Harith bin Aus and `Abbad bin Bishr). So Muhammad bin Maslama went in together with two men, and sail to them, "When Ka`b comes, I will touch his hair and smell it, and when you see that I have got hold of his head, strip him. I will let you smell his head." Ka`b bin Al-Ashraf came down to them wrapped in his clothes, and diffusing perfume. Muhammad bin Maslama said. " have never smelt a better scent than this. Ka`b replied. "I have got the best 'Arab women who know how to use the high class of perfume." Muhammad bin Maslama requested Ka`b "Will you allow me to smell your head?" Ka`b said, "Yes." Muhammad smelt it and made his companions smell it as well. Then he requested Ka`b again, "Will you let me (smell your head)?" Ka`b said, "Yes." When Muhammad got a strong hold of him, he said (to his companions), "Get at him!" So they killed him and went to the Prophet and informed him. (Abu Rafi`) was killed after Ka`b bin Al-Ashraf."

AbdurRahman ibn Ka'b ibn Malik said: When Ka'b ibn Malik heard the call to prayer on Friday, he prayed for As'ad ibn Zurarah. I asked him: What is the matter that when you hear the call to prayer, you pray for As'ad ibn Zurarah? He replied: This is because he held the Friday prayer for the first time for us at Hazm an-Nabit of Harrah belonging to Banu Bayadah in Naqi', called Naqi' al-Khadumat. I asked him: How many were you at that time ? He said: Forty.

Al-Hasan reported: Umar ibn al-Khattab gathered the people (in tarawih prayer) behind Ubayy ibn Ka'b (who led them). He used to lead them for twenty days (during Ramadan, and would not recite the supplication except in the second half of it (i.e. Ramadan). When the last ten days remained, he kept away from them, and prayed in his house. They used to say: Ubayy ran away.

Abu Dawud said: This tradition shows that whatever has been reported about the recitation of the supplication is not tenable. Moreover, these two traditions from Ubayy b. Ka'b indicate that another tradition which tells that the Prophet (saws) recited the supplication in the witr is weak.

This hadith has been narrated on the authority of Ibn Ka'b through another chain of transmitters but with " "the similitude of the disbeliever is that of a cypress tree".

Ibn 'Abbas has reported this hadith on the authority of Ubayy b. ka'b that Allah's Apostle (may peace be upon him) used to recite this.

'Abdullah b. Ka'b reported that his father Ka'b narrated to him that Allah's Messenger (may peace be upon him) used to eat with three fingers and when he had finished (eating), he licked them.

Ibn Ka'b b. Malik reported on the authority of his father that the Messenger of Allah (may peace be upon him) used to eat (food) with three fingers and he licked his hand before wiping it (with towel).

AbuThumamah al-Hannat said that Ka'b ibn Ujrah met him while he was going to the mosque; one of the two (companions) met his companion (on his way to the mosque) And he met crossing the fingers of my both hands. He prohibited me to do so, and said: The Messenger of Allah (saws) has said: If any of you performs ablution, and performs his ablution perfectly, and then goes out intending for the mosque, he should not cross the fingers of his hand because he is already in prayer.

Ibn Ka'b b. Malik reported on the authority of his father that he saw Allah's Messenger (may peace be upon him) licking his three fingers (after having finished the food). Ibn Hatim made no mention of" three". This hadith is also narrated through another chain of transmitters.

The Messenger of Allah (saws) as saying: The atonement for a vow is the same as for an oath.

Abu Dawud said: This tradition has also been transmitted by 'Amr b. al-Harith from Ka'b b. 'Alqamah, from Ibn Shamasah on the authority of 'Uqbah.

This hadith has been narrated by Husain with the same chain of transmitters, but no mention is made of Umm Ka'b.

A hadith like this has been reported on the authority of Ka'b b. Malik through another chain of transmitters.
