حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ يَعْلَى بْنِ عَطَاءٍ أَنَّهُ سَمِعَ عَلِيًّا الْأَزْدِيَّ يُحَدِّثُ أَنَّهُ سَمِعَ ابْنَ عُمَرَ يُحَدِّثُ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ صَلَاةُ اللَّيْلِ وَالنَّهَارِ مَثْنَى مَثْنَى وَكَانَ شُعْبَةُ يَفْرَقُهُ
