Sa'd ibn al-Rabi' ibn Amr al-Khazraji al-Ansari was a Companion of the Khazraj tribe of Medina; his mother Huzayla bint Utba was among the women who pledged allegiance to the Prophet. He was one of the few literate people of pre-Islamic Medina and served as a scribe, later being counted among the Prophet's scribes. He took part in the First and Second Pledges of Aqaba and was one of the chiefs (naqib) of the Ansar. After the Hijra the Prophet established a bond of brotherhood between Sa'd and Abd al-Rahman ibn Awf; Sa'd offered to share half his wealth and one of his two orchards, but Abd al-Rahman declined, asking only to be shown the market. Sa'd fought at Badr and Uhud, and was martyred at Uhud (3 AH / 625 CE) after receiving numerous wounds. The Prophet sent a Companion to find him; dying, Sa'd delivered his message to the Ansar: that they would have no excuse before God should harm reach the Prophet while one of them yet lived. His body was so mutilated it was recognized only by his fingers, and he was buried in the Cemetery of Uhud in a single grave together with Kharija ibn Zayd.
