The Prophet ﷺ said, "By the One in whose hand my soul rests, the son of Maryam will surely descend at Fajj al-Rawha as a pilgrim performing Hajj or Umrah, or both together."
عن النبي ﷺ قال: والذي نفسي بيده! ليهن ابن مريم بفج الروحاء حاجا أو معتمرا أو ليثنيتهما.
Muslim recorded it in the Hajj [chapter] (1252) through several routes from Ibn Shihab Zuhri, from Hanzala bin Ali Aslami, who said, "I heard Abu Hurairah," and then he related it.His saying, "he will surely perform them both together," is with a fatha on the ya at its beginning, meaning he will combine the two, and this will take place after Isa descends from the sky at the end of time. As for Fajj Rawha, it is with a fatha on the fa and a doubled jim. Hafiz Abu Bakr Hazimi said, "It lies between Makkah and Madinah." He said, "It was the route taken by the Messenger of Allah ﷺ to Badr, and to Makkah in the year of the Conquest, and in the year of the Farewell Hajj."See Nawawi's commentary on Muslim (8/233).
