The Prophet ﷺ said, "The Hour will not be established till you fight with people wearing shoes made of hair. And the Hour will not be established till you fight with people whose faces look like shields coated with leather. " (Abu Huraira added, "They will be) small-eyed, flat nosed, and their faces will look like shields coated with leather.")  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ تَقُومُ السَّاعَةُ حَتَّى تُقَاتِلُوا قَوْمًا نِعَالُهُمُ الشَّعَرُ وَلاَ تَقُومُ السَّاعَةُ حَتَّى تُقَاتِلُوا قَوْمًا كَأَنَّ وُجُوهَهُمُ الْمَجَانُّ الْمُطَرَّقَةُ قَالَ سُفْيَانُ وَزَادَ فِيهِ أَبُو الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ رِوَايَةً صِغَارَ الأَعْيُنِ ذُلْفَ الأُنُوفِ كَأَنَّ وُجُوهَهُمُ الْمَجَانُّ الْمُطْرَقَةُ
