Sahih Muslim Introduction 56
Hajjāj bin ash-Shā’ir narrated to me, Ahmad bin Yūnus narrated to us, he said, I heard Zuhayr saying, Jābir said, or, I heard Jābir saying:
‘Indeed I have fifty thousand Ḥadīth that I have not narrated from at all’. [Zuhayr] said: ‘Then that day he related a Ḥadīth and said, ‘This is from the fifty thousand’.
وَحَدَّثَنِي حَجَّاجُ بْنُ الشَّاعِرِ، حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، قَالَ سَمِعْتُ زُهَيْرًا، يَقُولُ قَالَ جَابِرٌ - أَوْ سَمِعْتُ جَابِرًا، يَقُولُ - إِنَّ عِنْدِي لَخَمْسِينَ أَلْفَ حَدِيثٍ مَا حَدَّثْتُ مِنْهَا بِشَىْءٍ ‏.‏ قَالَ ثُمَّ حَدَّثَ يَوْمًا بِحَدِيثٍ فَقَالَ هَذَا مِنَ الْخَمْسِينَ أَلْفًا ‏.‏
