وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي ح، وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ، بِشْرٍ قَالاَ حَدَّثَنَا عُبَيْدُ اللَّهِ، بِهَذَا الإِسْنَادِ ‏.‏ مِثْلَهُ وَزَادَ قَالَ عُبَيْدُ اللَّهِ فَسَأَلْتُهُ فَقَالَ قَرْيَتَيْنِ بِالشَّامِ بَيْنَهُمَا مَسِيرَةُ ثَلاَثِ لَيَالٍ ‏.‏ وَفِي حَدِيثِ ابْنِ بِشْرٍ ‏.‏ ثَلاَثَةِ أَيَّامٍ ‏.‏
