Abu Dawud Sulayman ibn al-Ash'ath al-Sijistani

Abu Dawud al-Sijistani was a Persian scholar of Arab descent born in Sistan. He lived during the 9th century CE and travelled extensively across the Islamic world, including Iraq, Egypt, Syria, Hijaz, and beyond, to collect hadith. His primary focus was on legal hadith to support Islamic jurisprudence. He compiled the Sunan Abu Dawud, containing approximately 4,800 hadith selected from a vast corpus. Abu Dawud died in 889 CE in Basra. His son, Abu Bakr Abdullah ibn Abu Dawud, was also a noted hadith scholar.
