وَمَا قُلْنَا مِنْ هَذَا مَوْجُودٌ فِي الْحَدِيثِ مُسْتَفِيضٌ مِنْ فِعْلِ ثِقَاتِ الْمُحَدِّثِينَ وَأَئِمَّةِ أَهْلِ الْعِلْمِ. وَسَنَذْكُرُ مِنْ رِوَايَاتِهِمْ عَلَى الْجِهَةِ الَّتِي ذَكَرْنَا عَدَدًا يُسْتَدَلُّ بِهَا عَلَى أَكْثَرَ مِنْهَا إِنْ شَاءَ اللَّهُ تَعَالَى.
Translation: This variation is attested among trustworthy hadith scholars, so Muslim introduces a selection of cases as evidence for the broader phenomenon.
An extra transmitter is not automatically proof that the shorter route is mistaken. The cases call for comparison of what each narrator actually transmitted.
