حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، ح قَالَ وَحَدَّثَنِيهِ يَحْيَى بْنُ حَبِيبٍ، حَدَّثَنَا خَالِدٌ، – يَعْنِي ابْنَ الْحَارِثِ – قَالاَ حَدَّثَنَا شُعْبَةُ، بِهَذَا الإِسْنَادِ وَفِي حَدِيثِ ابْنِ جَعْفَرٍ “ وَلاَ يَتَبَسَّطْ أَحَدُكُمْ ذِرَاعَيْهِ انْبِسَاطَ الْكَلْبِ ” .
This hadith has been narrated by Shu’ba with the same chain of transmitters. And in the hidith transmitted by Ibn Ja’far (the words are):
” None of you should stretch out his forearms like the stretching out of a dog.”
