«كَحَدِيثِ شُعَبِ الْإِيمَانِ»
Another example is the hadith about the branches of faith.
This discussion identifies singular transmission along Abu Salih from Abu Hurayrah and then ʿAbd Allah ibn Dinar from Abu Salih. The isolation can therefore extend across more than one consecutive link; there need not be only a single isolated position.
The relevant chain is read link by link:
Abu Hurayrah → Abu Salih → ʿAbd Allah ibn Dinar.
Recognizing consecutive isolated links demonstrates that singularity can persist through successive transmitters. The number of later chains does not replace this original link-by-link inquiry.
