Sahih Muslim 2912
Sahih Muslim · Book 54: The Book of Tribulations and Portents of the Last Hour · The Hour Will Not Begin Until A Man Passes By Another Man's Grave And Wishes That He Was In The Place Of The Deceased, Because Of Calamity
Abu Huraira reported Allah's Messenger (ﷺ) as saying:
حَدَّثَنَا أَبُو كُرَيْبٍ ، حَدَّثَنَا وَكِيعٌ ، وَأَبُو أُسَامَةَ عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ ، عَنْ قَيْسِ، بْنِ أَبِي حَازِمٍ عَنْ أَبِي هُرَيْرَةَ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تُقَاتِلُونَ بَيْنَ يَدَىِ السَّاعَةِ قَوْمًا نِعَالُهُمُ الشَّعَرُ كَأَنَّ وُجُوهَهُمُ الْمَجَانُّ الْمُطْرَقَةُ حُمْرُ الْوُجُوهِ صِغَارُ الأَعْيُنِ " .
You shall fight in the hours to come against a nation wearing shoes made of hair and faces like hammered shields, with red complexion and small eyes.
