Qur’an, hadith, and narrator evaluation
‘Ilm al-rijal evaluates transmitters and chains of transmission. Students investigate identities, reliability assessments, possible discontinuities, and disputed judgments about narrators. A report appearing in a major Shi‘i collection is not thereby automatically accepted as authentic by every Usuli jurist.
This is the science Sanad serves: what each book of rijal says about a narrator, attributed and located, with no verdict of its own.
