حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، أَنَّ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ حَدَّثَهُمْ أَنَّ النَّبِيَّ صلى الله عليه وسلم صَعِدَ أُحُدًا وَأَبُو بَكْرٍ وَعُمَرُ وَعُثْمَانُ فَرَجَفَ بِهِمْ فَقَالَ " اثْبُتْ أُحُدُ فَإِنَّمَا عَلَيْكَ نَبِيٌّ وَصِدِّيقٌ وَشَهِيدَانِ " .
