Arabic hadith text
وَحَدَّثَنِيهِ زُهَيْرُ بْنُ حَرْبٍ، وَيَعْقُوبُ الدَّوْرَقِيُّ، قَالاَ حَدَّثَنَا إِسْمَاعِيلُ، وَهُوَ ابْنُ عُلَيَّةَ عَنْ أَيُّوبَ، عَنْ مُحَمَّدٍ، قَالَ قَالَ أَبُو هُرَيْرَةَ " لاَ يَزَالُ النَّاسُ " . بِمِثْلِ حَدِيثِ عَبْدِ الْوَارِثِ غَيْرَ أَنَّهُ لَمْ يَذْكُرِ النَّبِيَّ صلى الله عليه وسلم فِي الإِسْنَادِ وَلَكِنْ قَدْ قَالَ فِي آخِرِ الْحَدِيثِ صَدَقَ اللَّهُ وَرَسُولُهُ
Translation
It is narrated on the authority of Abu Huraira that he said
The people will constantly, and the rest of the hadith is the same as that transmitted by 'Abdul-Warith with the exception that there is no mention of the Messenger of Allah in that, but he observed at the end of the hadith: Allah and His Messenger told the truth.
