His full name was Aamir ibn Abdullah ibn al-Jarrah. He was known as Abu Ubaydah (may Allah be pleased with him).

Of him Abdullah ibn Umar (may Allah be pleased with him), one of the companions of the Prophet, said:

"Three persons in the tribe of Quraysh were most prominent, had the best character and were the most modest. If they spoke to you, they would not deceive you and if you spoke to them, they would not accuse you of Lying: Abu Bakr as-Siddiq, Uthman ibn Affan and Abu Ubaydah ibn al-Jarrah."
