أَخْبَرَنَا أَبُو عَبْدِ الرَّحْمَنِ، أَحْمَدُ بْنُ شُعَيْبٍ قَالَ أَنْبَأَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا أَبُو عَاصِمٍ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، قَالَ حَدَّثَنِي أَسِيدُ بْنُ أَبِي أَسِيدٍ، عَنْ مُعَاذِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، قَالَ أَصَابَنَا طَشٌّ وَظُلْمَةٌ فَانْتَظَرْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم لِيُصَلِّيَ بِنَا ثُمَّ ذَكَرَ كَلاَمًا مَعْنَاهُ فَخَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِيُصَلِّيَ بِنَا فَقَالَ ‏
