حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَعَمْرُو بْنُ رَافِعٍ، قَالاَ حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَبِيدَةَ السَّلْمَانِيِّ، قَالَ قَالَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَىُّ النَّاسِ خَيْرٌ قَالَ " قَرْنِي ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ يَجِيءُ قَوْمٌ تَبْدُرُ شَهَادَةُ أَحَدِهِمْ يَمِينَهُ وَيَمِينُهُ شَهَادَتَهُ " .
