حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، - يَعْنِي ابْنَ مَهْدِيٍّ - حَدَّثَنَا شُعْبَةُ،
عَنْ عَلِيِّ بْنِ الأَقْمَرِ، عَنْ أَبِي الأَحْوَصِ، عَنْ عَبْدِ اللَّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ
" لاَ تَقُومُ السَّاعَةُ إِلاَّ عَلَى شِرَارِ النَّاسِ " .
The Last Hour would affect (most terribly) the wicked persons.
