Narrated Qais:
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.
