Sahih al-Bukhari 3591

Narrated Abu Huraira:

I enjoyed the company of Allah's Messenger (ﷺ) for three years, and during the other years of my life, never was I so anxious to understand the (Prophet's) traditions as I was during those three years. I heard him saying, beckoning with his hand in this way, "Before the Hour you will fight with people who will have hairy shoes and live in Al-Bazir." (Sufyan, the sub-narrator once said, "And they are the people of Al-Bazir.")

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ قَالَ إِسْمَاعِيلُ أَخْبَرَنِي قَيْسٌ، قَالَ أَتَيْنَا أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ فَقَالَ صَحِبْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم ثَلاَثَ سِنِينَ لَمْ أَكُنْ فِي سِنِيَّ أَحْرَصَ عَلَى أَنْ أَعِيَ الْحَدِيثَ مِنِّي فِيهِنَّ سَمِعْتُهُ يَقُولُ وَقَالَ هَكَذَا بِيَدِهِ ‏ "‏ بَيْنَ يَدَىِ السَّاعَةِ تُقَاتِلُونَ قَوْمًا نِعَالُهُمُ الشَّعَرُ، وَهُوَ هَذَا الْبَارِزُ ‏"‏‏.‏ وَقَالَ سُفْيَانُ مَرَّةً وَهُمْ أَهْلُ الْبَازَرِ‏.‏
