Sunan Abu-Dawud

Sunan Abu Dawood ( romanized: Sunan Abi Dawud) is one of the Kutub al-Sittah (six major hadith collections), collected by Abu Dawud al-Sijistani (d.889).It took Abu Dawod 20 years to collect the hadiths. He made a series of journeys to meet most of the foremost traditionists of his time and acquired from them the most
reliable hadiths, quoting sources through which it reached him. Since the author collected hadiths which no one had ever assembled together, his sunan has been accepted as a standard work by scholars from many parts of the Islamic world.
