Sahih Muslim Vol. 1, Book of Introduction, Hadith 79
Suwayd bin Sa’īd narrated to us, Alī bin Mus’hir narrated to us, he said:
‘Hamzah az-Zayyāt and I heard from Abān bin Abī Ayyāsh something like one thousand Ḥadīth’. Alī said: ‘So I met Hamzah then he informed me that he saw the Prophet ﷺ [in a dream], and he produced for him what he heard from Abān. However he [the Prophet] didn’t recognize any except a small amount [like] five or six [Ḥadīth]’.
وَحَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، قَالَ سَمِعْتُ أَنَا وَحَمْزَةُ الزَّيَّاتُ، مِنْ أَبَانَ بْنِ أَبِي عَيَّاشٍ نَحْوًا مِنْ أَلْفِ حَدِيثٍ . قَالَ عَلِيٌّ فَلَقِيتُ حَمْزَةَ فَأَخْبَرَنِي أَنَّهُ رَأَى النَّبِيَّ ﷺ فِي الْمَنَامِ فَعَرَضَ عَلَيْهِ مَا سَمِعَ مِنْ أَبَانَ فَمَا عَرَفَ مِنْهَا إِلاَّ شَيْئًا يَسِيرًا خَمْسَةً أَوْ سِتَّةً .
