I heard Abu Dhar swearing that these Holy Verses were revealed in connection with those six persons on the day of Badr.  

البخاري:٣٩٦٨ – حَدَّثَنَا يَحْيَى بْنُ جَعْفَرٍ أَخْبَرَنَا وَكِيعٌ عَنْ سُفْيَانَ عَنْ أَبِي هَاشِمٍ عَنْ أَبِي مِجْلَزٍ عَنْ قَيْسِ بْنِ عُبَادٍ

سَمِعْتُ أَبَا ذَرٍّ ؓ يُقْسِمُ لَنَزَلَتْ هَؤُلاَءِ الآيَاتُ فِي هَؤُلاَءِ الرَّهْطِ السِّتَّةِ يَوْمَ بَدْرٍ نَحْوَهُ
