«وَقَرِيبٌ مِنْ هَذَا اخْتِلَافُهُمْ فِي الْمُنْقَطِعِ وَالْمُرْسَلِ»
A comparable issue appears in how critics use the terms munqatiʿ and mursal.
Within hadith criticism, a technical noun may have a carefully defined sense while a related verb can be employed more broadly. Calling a report technically “mursal” and saying that a transmitter “sent it” do not invariably communicate identical degrees of specification.
The parallel matters because fard and gharib as classifications also have naming conventions that differ from the broader use of derived verbs. The detailed definitions of mursal and munqatiʿ belong to their own later discussion.
