It was narrated that ‘Amr bin Taghlib said:
“I heard the Prophet ﷺ say: ‘One of the portents of the Hour is that you fight people with broad faces, as if their faces are hammered shields. And one of hte portents of the Hour is that you will fight people who wear shoes of hair.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةُ، حَدَّثَنَا أَسْوَدُ بْنُ عَامِرٍ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، حَدَّثَنَا الْحَسَنُ، عَنْ عَمْرِو بْنِ تَغْلِبَ، قَالَ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ " إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ تُقَاتِلُوا قَوْمًا عِرَاضَ الْوُجُوهِ كَأَنَّ وُجُوهَهُمُ الْمَجَانُّ الْمُطْرَقَةُ وَإِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ تُقَاتِلُوا قَوْمًا يَنْتَعِلُونَ الشَّعَرَ " .
