Sunan Abi Dawud, Hadith 4290

Abu hurairah reported the Prophet as saying: The last hour will not come before you fight with a people whose sandals are of hair, and the Last hour will not come before you fight with a people who have small eyes, short noses, and whose faces look as if they were shields covered with skin.

حَدَّثَنَا قُتَيْبَةُ، وَابْنُ السَّرْحِ، وَغَيْرُهُمَا، قَالُوا حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، رِوَايَةً - قَالَ ابْنُ السَّرْحِ - أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ تَقُومُ السَّاعَةُ حَتَّى تُقَاتِلُوا قَوْمًا نِعَالُهُمُ الشَّعْرُ وَلاَ تَقُومُ السَّاعَةُ حَتَّى تُقَاتِلُوا قَوْمًا صِغَارَ الأَعْيُنِ ذُلْفَ الآنُفِ كَأَنَّ وُجُوهَهُمُ الْمَجَانُّ الْمُطْرَقَةُ ‏" ‏ ‏.‏
