Four sources

One notable characteristic of Shia Quranic exegesis is the focus on the narrative of the Ahlul Bayt (the family of the Prophet) and their exemplary virtues. This perspective inspires a rich tradition of commentary (tafsir) that highlights the interceding role of the Imams, underlining their significance in understanding complex moral and spiritual issues elucidated in the Quran. Moreover, the Quran is integral to the rituals and practices of Shia Islam, particularly in prayers (salat) and mournful commemorations, such as those observed during Muharram.

The Hadith

Hadith, or the recorded sayings and actions of the Prophet Muhammad, serves as the second pillar of Shia religious doctrine. These narrations, which delineate the life and teachings of the Prophet, are essential for comprehending principles that may not be explicitly stated in the Quran. Within Shia Islam, the Hadith literature is meticulously categorized, with a distinct focus on the narrations transmitted through the Ahlul Bayt.
