It was narrated from Abu Hurairah that the Messenger of Allah ﷺ said:

"The Hour will not begin until the Muslims fight the Turks, a people with faces like hammered shields who wear clothes made of hair and shoes made of hair."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا يَعْقُوبُ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " لاَ تَقُومُ السَّاعَةُ حَتَّى يُقَاتِلَ الْمُسْلِمُونَ التُّرْكَ قَوْمًا وُجُوهُهُمْ كَالْمَجَانِّ الْمُطَرَّقَةِ يَلْبَسُونَ الشَّعَرَ وَيَمْشُونَ فِي الشَّعَرِ " .
