Narrated Usama bin Zaid:As soon as the Prophet (ﷺ) departed from `Arafat, he went towards the mountain pass, and there he answered the call of nature. He was asked, "O Allah's Messenger (ﷺ)! Will you offer the prayer here?" He replied, "(The place of) the prayer is ahead of you (i.e. at Al-Muzdalifa)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
