Abu Dharr (RA) 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 bin Harith (from the side of the Muslims) and Utba and Shaiba, both of them the sons of Rabiah and Walid bin Utba (from the side of the non-believers of Makkah).
