حَدَّثَنِي عَمْرٌو النَّاقِدُ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا حَمَّادٌ، - وَهُوَ ابْنُ سَلَمَةَ - عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ أَهْلَ الْيَمَنِ، قَدِمُوا عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالُوا ابْعَثْ مَعَنَا رَجُلاً يُعَلِّمْنَا السُّنَّةَ وَالإِسْلاَمَ . قَالَ فَأَخَذَ بِيَدِ أَبِي عُبَيْدَةَ فَقَالَ " هَذَا أَمِينُ هَذِهِ الأُمَّةِ " .
