Is what is narrated about Ibn Mas'ud – may Allah be pleased with him – regarding the incident of Abu Jahl in Mecca and the event of his killing in the Battle of Badr, including Abu Jahl's torture of him, Ibn Mas'ud's ascent upon Abu Jahl's chest after he was wounded, the cutting off of his head, and the Prophet's – peace and blessings be upon him – saying: "Indeed, O Ibn Mas'ud, an ear for an ear, and the head is extra," authentic?

The circulating narration about Abu Jahl's torture of Ibn Mas'ud and some details of his killing is a composite of several hadiths, some of which are authentic, and others weak or without origin. Thus, Abu Jahl's torture of Ibn Mas'ud with a nail has no origin, though it has been reported that he did harm him. As for Abu Jahl's killing at the hands of the two sons of 'Afra', it is established in the Two Sahihs. However, Abu Jahl's saying, "You have ascended a difficult ascent, O little shepherd," and the narration of Ibn Mas'ud cutting off his head, both have weakness in their chains of transmission. Although some scholars have strengthened parts of them, carrying heads is not from the guidance of Muslims, and Abu Bakr al-Siddiq disapproved of it. The part related to Ibn Mas'ud dragging Abu Jahl's head and the Prophet's (peace be upon him) saying, "An ear for an ear, and the head is extra," has no origin. Caution must be exercised when transmitting hadiths and biographies, as not everything mentioned is authentic.
