‘Iyās bin Mu’āwiyah asked me saying: ‘Indeed I see that you love knowledge of the Qur’ān, so recite for me a Sūrah and explain it until I can reflect on what you know’. [Sufyān] said, so I did that, and [Iyās] said to me: ‘Memorize from me what I am about to say to you- Beware of abominations in Ḥadīth for indeed rarely does anyone convey them except he lowers himself and his Ḥadīth are denied’.’  

سَأَلَنِي إِيَاسُ بْنُ مُعَاوِيَةَ فَقَالَ إِنِّي أَرَاكَ قَدْ كَلِفْتَ بِعِلْمِ الْقُرْآنِ فَاقْرَأْ عَلَىَّ سُورَةً وَفَسِّرْ حَتَّى أَنْظُرَ فِيمَا عَلِمْتَ قَالَ فَفَعَلْتُ فَقَالَ لِيَ احْفَظْ عَلَىَّ مَا أَقُولُ لَكَ إِيَّاكَ وَالشَّنَاعَةَ فِي الْحَدِيثِ فَإِنَّهُ قَلَّمَا حَمَلَهَا أَحَدٌ إِلاَّ ذَلَّ فِي نَفْسِهِ وَكُذِّبَ فِي حَدِيثِهِ
