Sahih Muslim Introduction 59
Salamah narrated to me, al-Humaydī narrated to us, Sufyān narrated to us, he said:
‘I heard Jābir talking about something like 30,000 Ḥadīth [that] I did not regard as permissible to mention anything from, and that to me was like this and that [Ḥadīth].’ Muslim said, I heard Abū Ghassān Muhammad bin Amr ar-Rāzī say, ‘I asked Jarīr bin Abd il-Hamīd: ‘Did you meet al-Hārith bin Hasīrah? He said: ‘Yes, [he is a] Shaykh of lengthy silence; he persisted in a grave matter.’
وَحَدَّثَنِي سَلَمَةُ، حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، قَالَ سَمِعْتُ جَابِرًا، يُحَدِّثُ بِنَحْوٍ مِنْ ثَلاَثِينَ أَلْفَ حَدِيثٍ مَا أَسْتَحِلُّ أَنْ أَذْكُرَ مِنْهَا شَيْئًا وَأَنَّ لِي كَذَا وَكَذَا ‏.‏ 
قَالَ مُسْلِمٌ وَسَمِعْتُ أَبَا غَسَّانَ، مُحَمَّدَ بْنَ عَمْرٍو الرَّازِيَّ قَالَ سَأَلْتُ جَرِيرَ بْنَ عَبْدِ الْحَمِيدِ فَقُلْتُ الْحَارِثُ بْنُ حَصِيرَةَ لَقِيتَهُ قَالَ نَعَمْ ‏.‏ شَيْخٌ طَوِيلُ السُّكُوتِ يُصِرُّ عَلَى أَمْرٍ عَظِيمٍ ‏.‏
