وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا غُنْدَرٌ، عَنْ شُعْبَةَ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى وَابْنُ بَشَّارٍ، قَالَا: حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ
Translation: Abū Bakr ibn Abī Shaybah transmitted through Ghundar from Shuʿbah; after a change of chain, Muhammad ibn al-Muthannā and Ibn Bashshār transmit through Muhammad ibn Jaʿfar from Shuʿbah.
“Ḥ” marks a change of isnād. Ghundar is the sobriquet of Muhammad ibn Jaʿfar: the two presentations converge at Muhammad ibn Jaʿfar (Ghundar), who transmits from Shuʿbah. Reporting two openings does not imply two independent Prophetic texts.
