So the governor sent a delegation and a letter to the Prophet ﷺ. The Prophet ﷺ kept them waiting for fifteen nights, then said, “Return to your leader and tell him: ‘My Lord has slain your lord this very night.’”

Abu Bakr ibn ʿAyyāsh narrated—through Dāwūd ibn Abī Hind, from his father, from Abū Hurayrah—that Saʿd came to the Prophet ﷺ and said, “Chosroes has perished—” or he said, “has been killed.” The Prophet ﷺ replied, “May Allah curse Chosroes. The first people to be destroyed will be the Persians, then the Arabs.”

Muhammad ibn Yahyā reported: Yaʿqūb ibn Ibrāhīm told us, from his father, from Ṣāliḥ, who said that Ibn Shihāb related—and al-Layth also transmitted it from Yūnus, both from Ibn Shihāb, from Abū Salamah, the wording being that of Ṣāliḥ: “It reached me that while Chosroes was in the garden-palace of his kingdom, an emissary—or someone specially appointed—appeared before him and presented the truth. Chosroes was startled to see a man walking toward him with a staff in his hand. The man said, ‘O Chosroes, will you accept Islam before I break this staff?’ Chosroes answered, ‘Yes—only do not break it.’ The man turned and left. When he had gone, Chosroes summoned his chamberlains and asked, ‘Who gave that man permission to enter?’ They replied, ‘No one came in to you.’ Chosroes said, ‘You are lying,’ became angry with them, and rebuked them, then let the matter drop.

“At the turn of the year, the same man returned with the staff and repeated his words. Chosroes again called for the chamberlains and scolded them. When the following year arrived, the man came yet again with the staff and said, ‘O Chosroes, will you embrace Islam before I break the staff?’ Chosroes replied, ‘Do not break it.’ The man broke it, and Allah destroyed Chosroes at that very moment.”

Al-Zuhrī narrated, through Ibn al-Musayyab, from Abū Hurayrah, that the Messenger of Allah ﷺ said, “When Chosroes dies, there will be no Chosroes after him; and when Caesar dies, there will be no Caesar…”
