[Machine] Abu Dharr said about this verse "These two opponents disputed about their Lord" [Surah Al-Hajj, verse 19]: It was revealed about those who competed with each other.  

عَنْ أَبِي ذَرٍّ فِي هَذِهِ الْآيَةِ {هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ} [الحج 19] قَالَ «نَزَلَتْ فِي الَّذِينَ تَبَارَزُوا»  

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, ʿAli, Ubaida bin Al-Harith, ʿUtba and Shaiba----the two sons of Rabiʿa-- and Al-Walid bin ʿUtba. (Using translation from Bukhārī 3969)   

أَنَّ هَذِهِ الْآيَةَ {هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ} [الحج 19] نَزَلَتْ فِي الَّذِينَ تَبَارَزُوا يَوْمَ بَدْرٍ حَمْزَةُ وَعَلِيٌّ وَعُبَيْدَةُ بْنُ الْحَارِثِ وَعُتْبَةُ وَشَيْبَةُ ابْنَا رَبِيعَةَ وَالْوَلِيدُ بْنُ عُتْبَةَ  

[Machine] This verse was revealed about us and in our confrontation on the day of Badr. "These two opponents disputed regarding their Lord." [Surah Al-Hajj, 19]  

فِينَا نَزَلَتْ هَذِهِ الْآيَةُ وَفِي مُبَارِزَتِنَا يَوْمَ بَدْرٍ {هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ} [الحج 19]
