Sunan Abu’ Dawud is one of the six important and authentic collections (Sihah Sittah) of the Prophetic Traditions. Abu Dawud, following the practice of his time, travelled far and wide to collect Hadith. He visited Hijaz, Iraq, Khurasan, Egypt, Syria, Nishapur, Merv and Isfahan for the purpose. His proficiency in Hadith is accepted. He also had keen insight in law (fiqh). His Sunan, naturally, is replete with legal Traditions; it also indicates his point of view on various questions and his acumen in ijtihad.
