In the saying of the Prophet ﷺ, the faces shone.

Ḥajjāj b. Minhāl And ʿAffān > Ḥammād b. Salamah > Yaʿlá b. ʿAṭāʾ > ʿAbdullāh b. Yasār Abū Hammām > Abū ʿAbd al-Raḥman al-Fihrī

We were with the Messenger of Allah ﷺ in the Battle of Hunayn, and we were in a hot and intense day. So, we descended under the shade of the trees and he mentioned a story. Then, he took a handful of soil and struck their faces and said, "The faces were humiliated. Allah has granted victory to the polytheists." Ya'la then said: "His sons told me that their fathers said, 'There was not a single one of us left except that his eyes and mouth were filled with dust.'" – Strong Chain

حَدَّثَنَا حَجَّاجُ بْنُ مِنْهَالٍ وَعَفَّانُ قَالَا حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ يَعْلَى بْنِ عَطَاءٍ عَنْ عَبْدِ اللَّهِ بْنِ يَسَارٍ أَبِي هَمَّامٍ عَنْ أَبِي عَبْدِ الرَّحْمَنِ الْفِهْرِيِّ قَالَ

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فِي غَزْوَةِ حُنَيْنٍ فَكُنَّا فِي يَوْمٍ قَائِظٍ شَدِيدِ الْحَرِّ فَنَزَلْنَا تَحْتَ ظِلَالِ الشَّجَرِ فَذَكَرَ الْقِصَّةَ ثُمَّ أَخَذَ كَفًّا مِنْ تُرَابٍ قَالَ فَحَدَّثَنِي الَّذِي هُوَ أَقْرَبُ إِلَيْهِ مِنِّي أَنَّهُ ضَرَبَ بِهِ وُجُوهَهُمْ وَقَالَ «شَاهَتِ الْوُجُوهُ فَهَزَمَ اللَّهُ الْمُشْرِكِينَ» قَالَ يَعْلَى فَحَدَّثَنِي أَبْنَاؤُهُمْ أَنَّ أَبَاءَهُمْ قَالُوا فَمَا بَقِيَ مِنَّا أَحَدٌ إِلَّا امْتَلَأَتْ عَيْنَاهُ وَفَمُهُ تُرَابًا – إسناده قوي
