It is narrated from Muhammad bin Umar (al-Waqidi) that Sayyiduna Ka'b bin Malik bin Abi Ka'b (may Allah be pleased with him) was the poet of the Messenger of Allah (peace and blessings be upon him). His kunyah is reported to have been "Abu Abdullah". He took part in the Battle of Uhud, in which he received more than ten wounds and was severely injured. He did not take part in the Battle of Badr, but he took part in the Trench (Khandaq) and in all the battles with the Messenger of Allah (peace and blessings be upon him) except the Battle of Tabuk, because he stayed behind from it; and he is one of the three Companions whose repentance Allah accepted. Sayyiduna Ka'b bin Malik (may Allah be pleased with him) died in the year 50 AH, during the governorship of Mu'awiyah bin Abi Sufyan (may Allah be pleased with them both), and at that time he was seventy-seven years old.

Sa'd bin Ishaq narrates from his father, from his grandfather Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him), that when the repentance of Sayyiduna Ka'b bin Malik (may Allah be pleased with him) and his companions was accepted, the Messenger of Allah (peace and blessings be upon him) ordered him to pray two rak'ahs (or two prostrations).

It is narrated from Sayyiduna Ka'b bin Malik (may Allah be pleased with him) (he was present at the Pledge of Aqabah) that he said: We set out from Madinah with the pilgrims, and Sayyiduna al-Bara' bin Ma'rur (may Allah be pleased with him) said to us: "O people! I have formed an opinion, and by Allah, I do not know whether you will agree with me on it or not." We asked: What is it? He said: "I have decided that I will not leave this House (the Ka'bah) behind my back (that is, I will face the Ka'bah in prayer)."
