باب فَضْلِ الصَّحَابَةِ ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ الَّذِينَ يَلُونَهُمْ ‏‏
Sahih Muslim 2534 a

Abu Huraira reported Allah's Messenger (may, peace be upon him) as saying:

The best age of my Umma is one in which I was sent (by Allah as an Apostle), then the one next to that. (The narrator said): And Allah knows best whether he stated this third (time) or not. Then there would come people who would love (to look) bulky and they would hasten to the witness box before they are asked to bear witness.
حَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، عَنْ أَبِي بِشْرٍ، ح وَحَدَّثَنِي إِسْمَاعِيلُ، بْنُ سَالِمٍ أَخْبَرَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو بِشْرٍ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ خَيْرُ أُمَّتِي الْقَرْنُ الَّذِينَ بُعِثْتُ فِيهِمْ ثُمَّ الَّذِينَ يَلُونَهُمْ ‏"‏ ‏.‏ وَاللَّهُ أَعْلَمُ أَذَكَرَ الثَّالِثَ أَمْ لاَ قَالَ ‏"‏ ثُمَّ يَخْلُفُ قَوْمٌ يُحِبُّونَ السَّمَانَةَ يَشْهَدُونَ قَبْلَ أَنْ يُسْتَشْهَدُوا ‏"‏ ‏.‏
