‘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’.’
