Narrated Sa`id bin Al-Musaiyab:`Ali and `Uthman differed regarding Hajj-at-Tamattu` while they were at 'Usfan (a familiar place near Mecca). `Ali said, "I see you want to forbid people to do a thing that the Prophet (ﷺ) did?" When `Ali saw that, he assumed Ihram for both Hajj and `Umra
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.
