Narrated Abu Huraira:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْوَهَّابِ ، حَدَّثَنَا عَبْدُ الْعَزِيزِ ، أَخْبَرَنِي ثَوْرٌ ، عَنْ أَبِي الْغَيْثِ ، عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم " لَنَالَهُ رِجَالٌ مِنْ هَؤُلاَءِ ".
The Prophet (ﷺ) said. Then some men from these people would attain it."
