حَدَّثَنِي بِشْرُ بْنُ الْحَكَمِ، قَالَ: سَمِعْتُ يَحْيَى بْنَ سَعِيدٍ الْقَطَّانَ، ضَعَّفَ حَكِيمَ بْنَ جُبَيْرٍ وَعَبْدَ الْأَعْلَى، وَضَعَّفَ يَحْيَى بْنَ مُوسَى بْنِ دِينَارٍ، قَالَ: حَدِيثُهُ رِيحٌ. وَضَعَّفَ مُوسَى بْنَ دِهْقَانَ وَعِيسَى بْنَ أَبِي عِيسَى الْمَدَنِيَّ. قَالَ: وَسَمِعْتُ الْحَسَنَ بْنَ عِيسَى يَقُولُ: قَالَ لِيَ ابْنُ الْمُبَارَكِ: إِذَا قَدِمْتَ عَلَى جَرِيرٍ فَاكْتُبْ عِلْمَهُ كُلَّهُ إِلَّا حَدِيثَ ثَلَاثَةٍ، لَا تَكْتُبْ حَدِيثَ عُبَيْدَةَ بْنِ مُعَتِّبٍ، وَالسَّرِيِّ بْنِ إِسْمَاعِيلَ، وَمُحَمَّدِ بْنِ سَالِمٍ.
Translation: Bishr b. al-Ḥakam reports Yaḥyā al-Qaṭṭān weakening Ḥakīm b. Jubayr, ʿAbd al-Aʿlā, Mūsā b. Dīnār, Mūsā b. Dihqān, and ʿĪsā b. Abī ʿĪsā al-Madanī. He said of Mūsā’s reports, “His hadith is wind”—an expression of instability. The report also transmits Ibn al-Mubārak’s advice to write from Jarīr but exclude reports of ʿUbaydah b. Muʿattib, al-Sarī b. Ismāʿīl, and Muḥammad b. Sālim.
The Al-Bushra reading “wa-ḍaʿʿafa Yaḥyā **bna** Mūsā b. Dīnār” includes an extra *bna*. Al-Nawawī explicitly identifies it as a transmitted textual error: the intended syntax has Yaḥyā al-Qaṭṭān as critic and Mūsā b. Dīnār as the criticized narrator. The primary text is preserved verbatim while the grammatical problem is explained.
“His hadith is wind” is metaphorical criticism of unreliability.
