Related examples involve near-identical given names and patronymics. “Ayyūb ibn Sayyār” and “Ayyūb ibn Yasār” share the given name while the father’s name contains similar letters in a different order. Their phonetic resemblance must not be taken as proof that they designate one person.
Key questions: How do “Sayyār” and “Yasār” differ in letter order? Do the transmission histories agree in time and teachers? Is this a manuscript error or a genuine pair of different narrators? Without such checks, emending one name into another would be premature.
Each ambiguity must be classified by its actual source—reversal, graphic confusion, dots, or vocalization—rather than solved through one uniform shortcut.
