Haseen bin Tameem attacked him and Habib bin Mazahir came to meet his challenge. Habib dealt a blow on the front of his head, which sank in and Habib threw him down (from his horse). Then his companions came to his rescue and took him away. Habib bin Mazahir then said, “I swear that if we would have been similar to you in quantity or even half of that, you would have turned your back from us, O men of ill origin and impotents”!
That day Habib was saying: “I am Habib and my father is Mazahir, who is a horseman of the battlefield when it is fierce, you are well-equipped and large in quantity, but we are more obedient, forbearing (than you), our proofs are exalted while truth apparent, and (we are) more pious and penitent than you.”
Habib bin Mazahir attacked severely (Malhoof) until he had killed sixty-two men. (Tabari) Then a man from the clan of Tameem attacked him and dealt a blow with his sword on his head and killed him (May Allah’s Mercy and Blessings be upon him). The name of his murderer was Budayl bin Sareem, who was from Bani Aqafan. Then another man from the clan of Tameem attacked him with a lance and threw him on the ground. When he tried to stand up, Haseen bin Tameem struck him on the head with his sword and he (again) fell down, then the person from Bani Tameem alighted from his horse and cut off his head.
Seeing this Haseen said, “I too am a partner in his murder along with you”, to which he said, “By Allah! No one except me has killed him.” Haseen said, “Then give me his head so that I may hang it in the neck of my horse so that people may see and understand that I too have participated in his murder. Then you may take it back and carry it to the presence of Ubaydullah bin Ziyad, for I am not desirous of the reward (which he will offer you in lieu of the murder of Habib).”
