Grading: This hadith is "jayyid" (good) by virtue of its routes. The present chain may be graded hasan on account of Amr bin Abd al-Rahman, who is "Ibn Umayyah", the nephew of Ya'la bin Umayyah, as is specified in some chains of this report; he is not the grandson of Ya'la bin Umayyah. The correct form of his name is "Amr" (with a waw), not "Umar". He is a Tabi'i whom Ibn Hibban mentioned in "al-Thiqat" and whose hadith he recorded in his "Sahih". His father Abd al-Rahman bin Umayyah, if not a Companion, is at least a senior mukhadram Tabi'i, and he narrates from Umar bin al-Khattab. Ibn Fathun counted him among the Companions (as Ibn Hajar said in "al-Isabah" 4/288). Ibn Hajar said: We have stated more than once that whoever lived in the time of the Prophet (peace and blessings be upon him) and survived after him, and was from Quraysh or an ally of theirs, attended the Farewell Pilgrimage with the Prophet (peace and blessings be upon him). This hadith has also been narrated through two other routes.

Technical note / Defect ('illah): Yahya bin Ayyub is al-Ghafiqi, Uqayl is Ibn Khalid al-Ayli, and Ibn Shihab is Muhammad bin Muslim al-Zuhri.

Reference / Source: Ahmad (29/17958) narrated it from Hajjaj bin Muhammad al-Missisi; and al-Nasa'i (7743 and 8642) through the route of Shu'ayb bin al-Layth bin Sa'd. Both of them narrate it from al-Layth bin Sa'd, from Uqayl bin Khalid, from Ibn Shihab al-Zuhri, from Amr bin Abd al-Rahman bin Umayyah, from his father, from his brother Ya'la bin Umayyah.

Reference / Source: Ahmad (17962), al-Nasa'i (7734 and 8652) and Ibn Hibban (4864) narrated it through the route of Amr bin al-Harith al-Misri; and Ahmad (17963) through the route of Fulayh bin Sulayman. Both of them narrate it from Ibn Shihab al-Zuhri, from Amr bin Abd al-Rahman bin Umayyah, the nephew of Ya'la bin Umayyah (as Amr bin al-Harith specified), from his father, from his brother Ya'la.

Reference / Source: It has another route with Ibn Abi Shaybah (14/499), Abu al-Qasim al-Baghawi in "Mu'jam al-Sahabah" (2172), al-Tahawi in "Mushkil al-Athar" (2621) and Ibn Qani' in "Mu'jam al-Sahabah" (3/319), from Umm Yahya bint Ya'la, from her father. But the marfu' wording in it is: "There is no emigration (hijrah) after the Conquest, but rather jihad and intention."
Grading: Its chain is "hasan" as a corroborating and supporting report (in the mutaba'at and shawahid).

Reference / Source: It has another route with Ibn Abi Asim in "al-Ahad wa al-Mathani" (1172) from Mujahid, who said: Ya'la bin Umayyah brought his father to the Prophet (peace and blessings be upon him). Its narrators are thiqah (trustworthy), but it is apparently "mursal", and the marfu' wording in it is the same as the wording of the hadith of Umm Yahya.
