Narrated `Abdullah bin Ka`b bin Malik:Who was Ka`b's guide from among his sons when Ka`b became blind: I heard Ka`b bin Malik saying, "When some people remained behind and did not join Allah's Messenger (ﷺ) in the battle of Tabuk.." and then he described the whole narration and said, "Allah's Messenger (ﷺ) forbade the Muslims to speak to us, and so we (I and my companions) stayed fifty nights in that state, and then Allah's Messenger (ﷺ) announced Allah's acceptance of our repentance
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.
