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.
These books relate accounts taken from the life of the Islamic prophet Muhammad, his family, and his companions.
related from An-Nasa'i Abu Saeed al Khudri reported that he heard Muhammad say, "While I was asleep, I dreamt that people are brought to me, all of them wearing shirts.
