وَحَدَّثَنِي إِبْرَاهِيمُ بْنُ خَالِدٍ الْيَشْكُرِيُّ، قَالَ: سَمِعْتُ أَبَا الْوَلِيدِ يَقُولُ: سَمِعْتُ سَلَّامَ بْنَ أَبِي مُطِيعٍ يَقُولُ: سَمِعْتُ جَابِرًا الْجُعْفِيَّ يَقُولُ: عِنْدِي خَمْسُونَ أَلْفَ حَدِيثٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.
Translation: Through Ibrāhīm b. Khālid al-Yashkurī, Abū al-Walīd and Sallām b. Abī Muṭīʿ: I heard Jābir al-Juʿfī say: I have fifty thousand reports attributed to the Prophet ﷺ.
The second chain enables comparison of how Jābir’s claim was reported: both mention fifty thousand, but only the preceding account adds a later event. Parallel attestations to someone’s claim are not attestations to the authenticity of the alleged fifty thousand reports.
