Sahih Muslim Introduction 78
Al-Hasan al-Hulwānī narrated to us, he said, I heard Affān say, I heard Abū Awānah say:
‘A Ḥadīth did not reach me on authority of al-Hasan except I presented it to Abān bin Abī Ayyāsh , then he read it to me ’.
وَحَدَّثَنَا الْحَسَنُ الْحُلْوَانِيُّ، قَالَ سَمِعْتُ عَفَّانَ، قَالَ سَمِعْتُ أَبَا عَوَانَةَ، قَالَ مَا بَلَغَنِي عَنِ الْحَسَنِ، حَدِيثٌ إِلاَّ أَتَيْتُ بِهِ أَبَانَ بْنَ أَبِي عَيَّاشٍ فَقَرَأَهُ عَلَىَّ ‏.‏
