It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Every nation has a trustworthy one, and the trustworthy one of this nation is Abu Ubaydah bin al-Jarrah."
The Shaykh said: Abu Ubaydah was placed later in the allotment because of the distance of his lineage, not because of any lack of nobility. He is better than some of the close Qurashis (who were put before him).
