وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ، عَنِ الأَسْوَدِ بْنِ قَيْسٍ، بِهَذَا الإِسْنَادِ وَقَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي غَارٍ فَنُكِبَتْ إِصْبَعُهُ .
It has been narrated on the authority of Aswad b. Qais who said:
