Sahih Muslim 2910
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 Messengar (ﷺ) as saying:
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، أَخْبَرَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - عَنْ ثَوْرِ بْنِ، زَيْدٍ عَنْ أَبِي الْغَيْثِ ، عَنْ أَبِي هُرَيْرَةَ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ تَقُومُ السَّاعَةُ حَتَّى يَخْرُجَ رَجُلٌ مِنْ قَحْطَانَ يَسُوقُ النَّاسَ بِعَصَاهُ " .
The Last Hour would not come before a person of Qahtan comes forth driving people with his stick.
