Sahih Muslim 85 d

This hadith has been transmitted by Muhammad b. Bashshar, Muhammad b. Ja'far Shu'ba with this chain of narrators, with the addition that he pointed towards the house of 'Abdullah, but he did not mention his name for us.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، بِهَذَا الإِسْنَادِ مِثْلَهُ ‏.‏ وَزَادَ وَأَشَارَ إِلَى دَارِ عَبْدِ اللَّهِ وَمَا سَمَّاهُ لَنَا ‏.‏
