وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا عُمَرُ بْنُ عَلِيِّ بْنِ مُقَدَّمٍ، عَنْ سُفْيَانَ بْنِ حُسَيْنٍ، قَالَ: سَأَلَنِي إِيَاسُ بْنُ مُعَاوِيَةَ فَقَالَ: «إِنِّي أَرَاكَ قَدْ كَلِفْتَ بِعِلْمِ الْقُرْآنِ، فَاقْرَأْ عَلَيَّ سُورَةً، وَفَسِّرْ حَتَّى أَنْظُرَ فِيمَا عَلِمْتَ». قَالَ: فَفَعَلْتُ، فَقَالَ لِي: «احْفَظْ عَلَيَّ مَا أَقُولُ لَكَ: إِيَّاكَ وَالشَّنَاعَةَ فِي الْحَدِيثِ، فَإِنَّهُ قَلَّمَا حَمَلَهَا أَحَدٌ إِلَّا ذَلَّ فِي نَفْسِهِ، وَكُذِّبَ فِي حَدِيثِهِ».
Translation: Yaḥyā b. Yaḥyā narrated to us: ʿUmar b. ʿAlī b. Muqaddam informed us, on the authority of Sufyān b. Ḥusayn, who said: Iyās b. Muʿāwiyah asked me and said, “I see that you have become deeply devoted to knowledge of the Qurʾān. Recite a sūrah to me and explain it, so that I may see what you know.” He said: I did so. Then Iyās said to me, “Remember what I tell you: Beware of objectionable reports in ḥadīth, for seldom does anyone carry them without becoming diminished in his own esteem and being disbelieved in his narrations.”
This is a scholarly caution by the Successor Iyās, not a Prophetic ḥadīth. “Kalifta” denotes marked attachment; “al-shanāʿah” concerns objectionable, discrediting transmissions, not every unfamiliar technical point. Careless circulation damages the narrator’s standing and public trust.
