فَلَا بُدَّ مِنْ إِعَادَةِ الْحَدِيثِ الَّذِي فِيهِ مَا وَصَفْنَا مِنَ الزِّيَادَةِ، أَوْ أَنْ يُفَصَّلَ ذَلِكَ الْمَعْنَى مِنْ جُمْلَةِ الْحَدِيثِ عَلَى اخْتِصَارِهِ إِذَا أَمْكَنَ،
Thus the report containing that addition must be repeated, or, where possible, the relevant meaning may be separated from the report and quoted in an abridged form.
Imam Muslim allows two ways to preserve the material addition: (1) repeat the whole report when necessary, or (2) isolate the relevant part if its meaning remains sound. The limiting phrase is “if possible.”
Al-Nawawī clarifies the intensive reading of *yufaṣṣala*: separating the pertinent meaning from the complete report. Such separation is conditioned on reliable preservation, not unrestricted cutting of transmitted wording.
