The Sunnah is one of the two roots of Islamic study of religion.
Therefore, along with the Quran, the sunnah was revealed
=== Sunnah Salat ===In addition to being "the way" of Islam or the traditional social and legal custom and practice of the Islamic community, sunnah is often used as a synonym for mustahabb (encouraged) rather than wajib/fard (obligatory), regarding some commendable action (usually the saying of a prayer)
