(who was one of the Badr warriors) Gabriel came to the Prophet ﷺ and said, "How do you look upon the warriors of Badr among yourselves?" The Prophet ﷺ said, "As the best of the Muslims." or said a similar statement. On that, Gabriel said, "And so are the Angels who participated in the Badr (battle).  

عَنْ أَبِيهِ وَكَانَ أَبُوهُ مِنْ أَهْلِ بَدْرٍ قَالَ جَاءَ جِبْرِيلُ إِلَى النَّبِيِّ ﷺ فَقَالَ مَا تَعُدُّونَ أَهْلَ بَدْرٍ فِيكُمْ قَالَ مِنْ أَفْضَلِ الْمُسْلِمِينَ أَوْ كَلِمَةً نَحْوَهَا قَالَ وَكَذَلِكَ مَنْ شَهِدَ بَدْرًا مِنَ الْمَلاَئِكَةِ  

Rifaʿa was one of the warriors of Badr while (his father) Rafiʿ was one of the people of Al-ʿAqaba (i.e. those who gave the pledge of allegiance at Al-ʿAqaba). Rafiʿ used to say to his son, "I would not have been happier if I had taken part in the Badr battle instead of taking part in the 'Aqaba pledge."  

سَأَلَ جِبْرِيلُ النَّبِيَّ ﷺ بِهَذَا  

The one who asked (the Prophet) was Gabriel (refer to Hadith 5.327).  

أَنَّ مَلَكًا سَأَلَ النَّبِيَّ ﷺ وَعَنْ يَحْيَى أَنَّ يَزِيدَ بْنَ الْهَادِ أَخْبَرَهُ أَنَّهُ كَانَ مَعَهُ يَوْمَ حَدَّثَهُ مُعَاذٌ هَذَا الْحَدِيثَ فَقَالَ يَزِيدُ فَقَالَ مُعَاذٌ إِنَّ السَّائِلَ هُوَ جِبْرِيلُ عَلَيْهِ السَّلاَمُ  

The Prophet ﷺ said on the day (of the battle) of Badr, "This is Gabriel holding the head of his horse and equipped with arms for the battle.  

أَنَّ النَّبِيَّ ﷺ قَالَ يَوْمَ بَدْرٍ هَذَا جِبْرِيلُ آخِذٌ بِرَأْسِ فَرَسِهِ عَلَيْهِ أَدَاةُ الْحَرْبِ
