Taṣḥīf and taḥrīf frequently appear in matn wording, but they can also affect the names within chains. Unfamiliar Arabic names, early manuscripts without dots, and careless reading may contribute. Biographical references, established spellings, manuscript witnesses, and independent transmission routes help establish the correct reading.
Three safeguards:
1. Compare independent routes and reliable textual witnesses for the disputed word.
2. Use known narrator identities and linguistic sense as evidence, not as the only proof.
3. Do not silently alter an original report to produce a preferred wording.
Keep the transmitted text distinct from explanatory commentary. Abbreviation and narration by meaning have their own technical conditions and should be studied separately. This preserves the distinctions among mudraj, maqlūb, mazīd, muḍṭarib, and muṣaḥḥaf/muḥarraf.
