Abu Sa'īd al-Khūdrī

Abū Saʿīd Saʿd ibn Mālik ibn Sinān al-Khazrajī al-Khudrī (Arabic: أبو سعيد سعد بن مالك بن سنان الخزرجي الخدري) was an inhabitant of Medina and early ally (Ansari) of the Islamic prophet Muhammad and one of the younger "companions of the prophet". Too young to fight at the Battle of Uhud in 625 where his father Malik ibn Sinan fell, he participated in subsequent campaigns. Although he traveled to Syria once to visit the Umayyad caliph Mu'awiya, he resided in Medina all his life. Later, he is said to have participated with his fellow Medinans in the defense of their city against the Umayyad army at the Battle of al-Harrah in 64/683. He is said variously to have died in 63/682, 64/683, 65/684, or 74/693. Abu Saʽid is one of the narrators of hadith most frequently quoted. By one count, he has 1170 narrations, making him the seventh most prolific Companion in the transmission of the hadith.

Shia Muslims do not automatically dismiss his narrations but compare what he narrates with other sources.
