حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ تَقُومُ السَّاعَةُ حَتَّى يُقَاتِلَ الْمُسْلِمُونَ التُّرْكَ قَوْمًا وُجُوهُهُمْ كَالْمَجَانِّ الْمُطْرَقَةِ يَلْبَسُونَ الشَّعَرَ وَيَمْشُونَ فِي الشَّعَرِ ‏"‏ ‏.‏

Abu Huraira reported Allah's Messenger (ﷺ) as saying: The Last Hour would not come until the Muslims fight with the Turks-a people whose faces would be like hammered shields wearing clothes of hair and walking (with shoes) of hair.
