When the Prophet ﷺ passed away, ʿAmr was serving as governor of ʿUmān, and a letter from Abū Bakr reached him announcing the death of the Messenger of Allah ﷺ.

Al-Layth narrated—from Khālid ibn Yazīd, from Saʿīd ibn Abī Hilāl, from Saʿīd ibn Nushayṭ—that Qurrah ibn Hubayrah came to the Messenger of Allah ﷺ and embraced Islam … the report. (1)

It also states that the Prophet appointed ʿAmr over al-Baḥrayn, and that he died while still there.

ʿAmr continued: “I set out until I passed by Musaylimah. He granted me safe-conduct and then said, ‘Muhammad was sent for weighty matters, whereas I have been sent for trifles.’

“I said, ‘Recite to me what you claim.’

“So he said:
‘O frog, croak away! How excellent is your croaking;
You neither deplete the water nor do you muddy it.’

“He then said:
‘O hyrax, O hyrax! Two forelegs and a chest—
How clearly its form is shown by the digging of its nest.’

“Next some people were brought to him, disputing over date-palms that some of them had cut down. He wrapped himself in a cloak, uncovered his head, and declared:
‘By the pitch-black night and the grey wolf,
Ibn Abī Muslim has not come here as a criminal.’

“He then covered himself a second time and said:
‘By the deepest night and the prowling wolf,
Its fresh dates are no more inviolable than its dry ones.
Go— I see no blame in what you have done.’ (2)

“I said, ‘By Allah, you are a liar, and you know full well that you are among the liars.’ So he threatened me.” (3)
