question #3 Sahih al-Bukhari 3969, Book 64, Hadith 22 : How does the revelation of specific Quranic verses relate to historical events in Islam?

I heard Abu Dhar swearing that the following Holy verse:– “These two opponents (believers and
disbelievers) disputing with each other about their Lord,” (22.19) was revealed concerning those men
who fought on the day of Badr, namely, Hamza, `Ali, Ubaida bin Al-Harith, `Utba and Shaiba—-the
two sons of Rabi`a– and Al-Walid bin `Utba.
