The Messenger of Allah ﷺ stood up to deliver a sermon in this valley and said, "Indeed, Amra has been incorporated into the Hajj until the Day of Resurrection."
حدثنا أبو بكر بن أبي شيبة وعلي بن محمد قالا حدثنا وكيع عن مسعر عن عبد الملك بن ميسرة عن طاوس

Sourcing, sahih. Nasai reported it, Rites of Hajj, chapter on the permissibility of converting Hajj into Umrah for one who has not brought the sacrificial animal, hadith no. 2808, from the narration of Abdul-Malik with this chain. Busiri said, this isnad is sahih, its narrators are trustworthy if it is free from disconnection, meaning between Tawus and Suraqah. Jabir bin Abdullah Ansari corroborated him, narrating from Suraqah with this wording, as found in Tabarani, 7/199. Its origin is in Sahih Muslim, hadith no. 2648. See also the previous hadith.
