Narrated Abu Sa`id:The Prophet (ﷺ) was more shy (from Haya': pious shyness from committing religeous indiscretions) than a veiled virgin girl. (See Hadith No. 762, Vol)
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.
