حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو هَاشِمٍ، عَنْ أَبِي مِجْلَزٍ، عَنْ قَيْسٍ، قَالَ سَمِعْتُ أَبَا ذَرٍّ، يُقْسِمُ قَسَمًا إِنَّ هَذِهِ الآيَةَ {هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ } نَزَلَتْ فِي الَّذِينَ بَرَزُوا يَوْمَ بَدْرٍ حَمْزَةَ وَعَلِيٍّ وَعُبَيْدَةَ بْنِ الْحَارِثِ وَعُتْبَةَ وَشَيْبَةَ ابْنَىْ رَبِيعَةَ وَالْوَلِيدِ بْنِ عُتْبَةَ.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
