The six collections above are the ones most Sunni Muslims regard as reliable enough to serve as a basis for Islamic law. They are not equal in weight — Sahih al-Bukhari and Sahih Muslim are considered more authoritative than the four Sunan works. A hadith's appearance in multiple canonical collections raises its standing.
Shia Muslims use a different set of primary collections (al-Kafi, Man La Yahduruhu al-Faqih, Tahdhib al-Ahkam, al-Istibsar). This catalog currently focuses on Sunni sources because they are the majority tradition and the most influential in global Islamic thought. Shia sources may be added later.
