al-Walid bin Muslim al-Quraishi الوليد بن مسلم القرشي · The Book of Hajj

"This is what I saw the Messenger of Allah doing."

Abu Bakr sent him, during the Hajj that the Messenger of Allah appointed him to lead before the Farewell Pilgrimage, with a group of other to announce to the people: "No idolater is to perform Hajj after this year, and no one is to circumambulate the House naked."
