وَقَالَ مُحَمَّدٌ: سَمِعْتُ عَلِيَّ بْنَ شَقِيقٍ، يَقُولُ: سَمِعْتُ عَبْدَ اللَّهِ بْنَ الْمُبَارَكِ، يَقُولُ عَلَى رُءُوسِ النَّاسِ: «دَعُوا حَدِيثَ عَمْرِو بْنِ ثَابِتٍ، فَإِنَّهُ كَانَ يَسُبُّ السَّلَفَ».
Translation: Muḥammad related through ʿAlī b. Shaqīq that Ibn al-Mubārak publicly warned: “Leave the reports of ʿAmr b. Thābit, for he used to revile the early generations.”
This is a historical criticism of a named transmitter, tied to stated conduct. The narrator-specific evidentiary judgment should not be mechanically generalized to every person whose theological views differ.
