The Last Hour would not come until a people wearing shoes of hair fight against you having their faces like hammered shields. (Using translation from Muslim 2912b)
قَالَ رَسُولُ اللهِ ﷺ لَا تَقُومُ السَّاعَةُ حَتَّى يُقَاتِلَكُمْ قَوْمٌ يَنْتَعِلُونَ الشَّعْرَ وُجُوهُهُمْ كَالْمَجَانِّ الْمُطْرَقَةِ
