Muslim Scholars: Abu Dawud Sulaymān ibn al-Ash‘ath: known as Abu Dawud, was a Persian scholar who compiled the third of the six “canonical” hadith collections recognized by Sunni Muslims, the Sunan Abu Dāwūd.
Abu Dawud was born in Sistan, eastern Iran and died in 889 in Basra. Many Scholars believe he was born in Baluchistan and later moved to Khorasan. He was primarily interested in jurisprudence, and as a result, his collection focused largely on legal hadith. He chose 4,800 for inclusion in his work.
