A sequence like “Sulaymān from Sulaymān” may contain two distinct narrators with the same given name. Repeated forms of this kind may even appear more than once in an extended chain.
If only shortened names are retained, a reader may assume the second occurrence is meaningless duplication or an error of transcription.
Each name must be expanded, where possible, with the father’s name, kunya, nisba, and teacher–pupil connection. This prevents an unwarranted “correction” from deleting a genuine chain link.
