—even if I heard the Messenger of Allah ﷺ himself say it, I would still reject it.

ʿĀṣim al-Aḥwal said: “I fell asleep and saw in a dream ʿAmr ibn ʿUbayd scraping away a verse of the Qur’an. I reproached him, whereupon he asked, ‘Shall I restore it?’ I replied, ‘Restore it.’ He said, ‘I cannot.’

Ḥammād ibn Zayd reported: “It was said to Ayyūb that ʿAmr ibn ʿUbayd had transmitted from al-Ḥasan the report that the Messenger of Allah ﷺ said, ‘When you see Muʿāwiyah on my pulpit, kill him.’ Ayyūb answered, ‘That is a lie.’”

Ibn ʿUlayyah stated: “The first person to speak of iʿtizāl was Wāṣil the weaver; ʿAmr ibn ʿUbayd joined him, was impressed by him, and married his sister.”

Muḥammad ibn ʿAbd Allāh al-Anṣārī related that he saw ʿAmr ibn ʿUbayd in a dream, transformed into a monkey.

Al-Manṣūr used to venerate Ibn ʿUbayd and would say:
All of you walk so slow,
All of you hunt for show,
Except ʿAmr ibn ʿUbayd.

I say: He was taken in by the man’s asceticism and sincerity, and overlooked his innovation.

Al-Khaṭīb said: “He died on the road to Mecca in the year 143 AH.”
Others said: “In 144 AH.”

Aḥmad ibn Abī Khaythamah records in his History: “I heard Ibn Maʿīn say: ʿAmr ibn ʿUbayd was one of the dahrīs (1).”

Sallām ibn Abī Muṭīʿ remarked: “I have more hope for al-Ḥajjāj than I do for ʿAmr ibn ʿUbayd.”
