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).
حَدَّثَنَا عَمْرُو بْنُ زُرَارَةَ، حَدَّثَنَا هُشَيْمٌ، عَنْ أَبِي هَاشِمٍ، عَنْ أَبِي مِجْلَزٍ، عَنْ قَيْسِ، بْنِ عُبَادٍ قَالَ سَمِعْتُ أَبَا ذَرٍّ، يُقْسِمُ قَسَمًا إِنَّ { هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ} إِنَّهَا نَزَلَتْ فِي الَّذِينَ بَرَزُوا يَوْمَ بَدْرٍ حَمْزَةُ وَعَلِيٌّ وَعُبَيْدَةُ بْنُ الْحَارِثِ وَعُتْبَةُ وَشَيْبَةُ ابْنَا رَبِيعَةَ وَالْوَلِيدُ بْنُ عُتْبَةَ .
