وَعَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ يَوْمَ بَدْرٍ: «هَذَا جِبْرِيلُ آخِذٌ بِرَأْسِ فرسه عَلَيْهِ أَدَاة الْحَرْب» . رَوَاهُ البُخَارِيّ
He told that the Prophet said on the day of Badr, "This is Gabriel holding his horse's head with the accoutrements of war on him." Bukhari transmitted it.
