Abu Dharr took an oath that this verse:" These two adversaries who dispute about their Lord" (xxii. 19) was revealed in connection with those who on the Day of Badr came out (of rows to fight against the non-believers and they were) Hamza, 'Ali, 'Ubaida b. Harith (from the side of the Muslims) and 'Utba and Shaiba, both of them the sons of Rabi'a and Walid b. 'Utba (from the side of the non-believers of Mecca)
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 Muslim is accepted as Sahih (authentic) by the established status of the book.
