As a follow-on to the discussion the obelus as a way to mark potentially incorrect passages included in Homeric texts…
“…refers to what most Muslims and the mainstream schools of Islamic thought, believe to be a record of the words, actions, and the silent approval of the Islamic prophet Muhammad as transmitted through chains of narrators. In other words, the ḥadīth are transmitted reports attributed to what Muhammad said and did.”
And same source:
“Unlike the Quran, not all Muslims believe that hadith accounts (or at least not all hadith accounts) are divine revelation. Different collections of hadīth would come to differentiate the different branches of the Islamic faith. Some Muslims believe that Islamic guidance should be based on the Quran only, thus rejecting the authority of hadith;…”
“Centuries ago, Arabia did not have schools for formal education. Students went to masters who taught them. Upon completion of their study, they received ijazah (permission) which acted as the certification of their education. A graduate then acted as a master having his own students or disciples. This chain of masters was known as silsila or lineage. Somewhat analogous to the modern situation where degrees are only accepted from recognized universities, the certification of a master having a verifiable chain of masters was the only criteria which accorded legitimacy…”
“For Muslims, the Chain of Authenticity is an important way to ascertain the validity of a saying of Muhammad (also known as a Hadith). The Chain of Authenticity relates the chain of people who have heard and repeated the saying of Muhammad through the generations, until that particular Hadith was written down (Ali bin Abi Talib said that ‘Aisha said that the Prophet Muhammad said…). A similar idea appears in Sufism in regards to the lineage and teachings of Sufi masters and students. This string of master to student is called a silsila, literally meaning “chain”. The focus of the silsila like the Chain of Authenticity is to trace the lineage of a Sufi order to Muhammad through his Companions: Ali bin Abi Talib (the primary link between all Sufi orders and Muhammad) and Abu Bakr (only the Naaqshbandiyyah order). When a Sufi order can be traced back to Muhammad through one Ali or Abu Bakr, the lineage is called the Silsilat al-Dhahab (dhahab meaning gold) or the “Chain of Gold” (Golden Chain).”
The thing that strikes me here is that both this and the obelus in Homeric literature serve the function of attempting to retain accurate oral (and later written) traditions across generations. Also authenticity. Some concepts buried in here that might positively impact modern attempts at human versus AI attribution in texts.
