The Messenger of Allah ﷺ said, "By the One in whose hand is the soul of Muhammad, the son of Mary will surely enter the valley of Rawha pronouncing the talbiyah for Hajj, or for Umrah, or for both together."
حدثنا سفيان عن الزهري عن حنظلة الأسلمي
قال رسول الله ﷺ والذي نفس محمد بيده ليهلن ابن مريم بفج الروحاء حاجا أو معتمرا أو ليثنينهما
Its isnad is sahih. Hanzala Aslami is Hanzala bin Ali bin Asqa Sulami Madani, a trustworthy tabii. Nasai and others rated him trustworthy, and Bukhari wrote a biographical entry on him in al-Kabir 1/35/2-36, as did Ibn Abu Hatim in al-Jarh wal-Tadil 1/239/2-240, and Ibn Saad in al-Tabaqat 5:186.Muslim narrated the hadith in 1:356-357 through Sufyan bin Uyayna with this same isnad. He then also narrated it through Layth, and through Yunus, both of them from Zuhri, in similar fashion. It will come again through other routes, both at length and in shortened form, at 7667, 7890, 10671, 10987. Ibn Kathir quoted it in his tafsir 3:15 from this very place in the Musnad. See also, regarding the descent of Isa, , what came earlier at 7267.As for Fajj Rawha, Yaqut said it lies between Makkah and Madinah, and it was the route the Messenger of Allah ﷺ took to Badr, and to Makkah in the year of the Conquest, and in the year of the Hajj.
