Abū ʿUmar al-Namirī said, “Abū al-Sāʾib accepted Islam after thirteen men had already done so, undertook both emigrations, and passed away sometime after Badr. He was a devoted, painstaking worshipper ⦗1⦘, and he, ʿAlī, and Abū Dharr once thought of castrating themselves ⦗2⦘.

Among the mursal reports of ʿUbayd Allāh ibn Abī Rāfiʿ is the statement: “The first person to be buried in Baqīʿ al-Gharqad was ʿUthmān ibn Maẓʿūn. The Messenger of Allah ﷺ placed a stone at the head of his grave and said, ‘This is the grave of the one who has gone on ahead of us ⦗3⦘.’ ”

He was also one of those who had already declared wine unlawful in the pre-Islamic period.

Ibn al-Mubārak narrated—through ʿUmar ibn Saʿīd, from Ibn Sābiṭ—that ʿUthmān ibn Maẓʿūn said: “I will not drink a beverage that robs me of my intellect, causes someone inferior to me to laugh at me, and leads me to marry off my noble daughter.”

When wine was later prohibited, he exclaimed, “Away with it! I had seen the matter plainly all along ⦗4⦘.”

This report is disconnected and cannot be established, and in fact wine was forbidden only after his death ⦗5⦘.
