Full Sharh — Musnad Ahmad 24
حَدَّثَنَا يَعْقُوبُ، حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، قَالَ قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي رَجُلٌ، مِنْ الْأَنْصَارٍ غَيْرُ مُتَّهَمٍ أَنَّهُ سَمِعَ عُثْمَانَ بْنَ عَفَّانَ، يُحَدِّثُ أَنَّ رِجَالًا، مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِينَ تُوُفِّيَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَزِنُوا عَلَيْهِ حَتَّى كَادَ بَعْضُهُمْ أَنْ يُوَسْوِسَ قَالَ عُثْمَانُ فَكُنْتُ مِنْهُمْ فَذَكَرَ مَعْنَى حَدِيثِ أَبِي الْيَمَانِ عَنْ شُعَيْبٍ.
