Thābit al-Bunānī narrated—on the authority of ʿIkrimah—that:

When Muṣʿab ibn ʿUmayr arrived in Madinah teaching the people, ʿAmr ibn al-Jamūḥ sent for him and asked, “What is this that you have brought us?”

They replied, “If you wish, we will come to you and let you hear the Quran.”

He said, “Yes.”

So Muṣʿab recited the opening part of Sūrat Yūsuf. ʿAmr said, “We have a matter to confer about with our people”—and he was the chief of Banū Salamah—so they left.

He then entered upon his idol, Manāf (1), and said, “O Manāf! By Allah, you know that the people want nothing but you. Have you any power to resist them?”

He hung a sword around the idol’s neck and went out, but his family rose and removed the sword.

When he returned he said, “Where is the sword, O Manāf? Shame on you! Even a nanny-goat defends her hind-quarters. By Allah, I see no good in this Abū Jiʿār tomorrow!”

Then he said to them, “I am going out to my property; look after Manāf well.”

As soon as he left, they smashed the idol, tied it to a dead dog, and threw the two into a well.

When he came back he asked, “How are you?”

They replied, “We are well, our master; Allah has cleansed our houses of all impurity.”

He said, “By Allah, I see you have been remiss in taking my place with respect to Manāf.”

They said, “Indeed so—look at him in that well.”

He leaned over, saw the idol, and sent for his clan. When they gathered he asked, “Are you not still upon what I am upon?”

They answered, “Indeed, you are our leader.”

He said, “Then bear witness that I have believed in what has been sent down to Muhammad.”

He continued: When the Day of Uḥud came, the Messenger of Allah ﷺ said, “Rise toward a Garden as wide as the heavens and the earth, prepared for the God-fearing.”

Though he was lame, ʿAmr stood up and said, “By Allah, I shall surely leap (2) toward it in Paradise!” Then he fought until he was killed.

And ʿĀṣim ibn ʿUmar reported that the Islam of ʿAmr ibn al-Jamūḥ was delayed. He had an idol called Manāf, while the youths of Banū Salamah had already believed; they would wait until night had fallen
