Sunan Abi Daawud (Arabic: ??? ??? ?????) is one of the Sunni Six Major Hadith collections, collected by Abu Dawood.
Abu Dawood Sulayman ibn Ash`ath al-Azadi al-Sijistani, commonly known as Abu Dawud, was a noted Khurassian collector of prophetic hadith, and wrote the third of the six canonical hadith collections, Sunan Abu Dawood.
He was born in Sijistan, now known as Sistan in south-western Afghanistan, in 817, and died in 888. Widely travelled among scholars of ahadith, he went to Iraq, Egypt, Syria, Saudi Arabia, Khurasan, Nishapur, and Marv among other places in order to collect hadith. He was primarily interested in jurisprudence, and as a result the collection by him focuses largely on legal hadith. Out of about 50,000 hadith, he chose 4,800 for inclusion in his work.
