In Ibn Ṣāliḥ’s version there is an additional detail: he put the robe on, and I saw him wearing it while standing on the pulpit. I had never seen anyone look finer than he did in it that day. He then gave it to Usāmah.

When Ḥakīm later saw it on Usāmah he said, “Usāmah! Are you wearing the robe of Dhū Yazan?”
He replied, “Yes, by Allah, I am better than he was, and my father is better than his.”
I then set out for Mecca and repeated his words, and the Meccans were impressed by them.

Al-Wāqidī, on the authority of al-Ḍaḥḥāk ibn ʿUthmān from his family, reported that Ḥakīm said:
“I was a merchant who travelled to Yemen and to Syria; I used to make large profits and would bring them back to the poor of my tribe.

“At the ʿUkāẓ market I bought Zayd ibn Ḥārithah for my aunt for six hundred dirhams. When the Messenger of Allah ﷺ married her, she gave Zayd to him, and he set him free.

“When Muʿāwiyah came for Ḥajj he took my house in Mecca for forty thousand dinars. I heard that Ibn al-Zubayr remarked, ‘That old man does not realise what he has sold.’ I said, ‘By Allah, I had only bought it for a wineskin of wine.’

“He never turned away anyone who came to him seeking assistance for a journey; he always supplied him (1).”

Al-Zubayr related through Ibrāhīm ibn Ḥamzah:
“When the idolaters of Quraysh confined Banū Hāshim in the mountain pass, caravans laden with wheat would reach Ḥakīm. He would drive them (2) toward the pass, strike their hindquarters, and they would go in, whereupon the besieged would take what they carried.”

Ibn Jurayj, on the authority of ʿAṭāʾ, narrated that when the Messenger of Allah ﷺ drew near Mecca he said:
“Four people I absolve of polytheism: ʿAttāb ibn Asīd, Jubayr ibn Muṭʿim, Ḥakīm ibn Ḥizām, and Suhayl ibn ʿAmr (3).”

I say: They embraced Islam, and their Islam was sound.
