Sahih Muslim intro-77
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 .
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 ’.
