فَإِذَا نَحْنُ تَقَصَّيْنَا أَخْبَارَ هَذَا الصِّنْفِ مِنَ النَّاسِ أَتْبَعْنَاهَا أَخْبَارًا يَقَعُ فِي أَسَانِيدِهَا بَعْضُ مَنْ لَيْسَ بِالْمَوْصُوفِ بِالْحِفْظِ وَالْإِتْقَانِ كَالصِّنْفِ الْمُقَدَّمِ قَبْلَهُمْ
Translation: After exhausting the reports of the first class, we will follow them with reports containing some transmitters who do not possess the same level of preservation and precision as the first rank.
This establishes an order of preference, not a rule that all later-mentioned reports are automatically rejected. Stronger routes are presented first; the next rank must still be evaluated on its own merits.
