Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا يَعْقُوبُ، 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 الْمُطَرَّقَةِ يَلْبَسُونَ الشَّعَرَ وَيَمْشُونَ فِي الشَّعَرِ " .
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."
