Musannaf Ibn Abi Shaybah 34472 — The virtue of Abu Ubaydah

Sayyiduna Hudhayfah (may Allah be pleased with him) said: Two bishops of Najran, al-Aqib and al-Sayyid, came to the Prophet (peace and blessings be upon him). They said: "Send with us a man who is fully trustworthy." The Companions of the Prophet (peace and blessings be upon him) began to hope for this. He (peace and blessings be upon him) said: "O Abu Ubaydah bin al-Jarrah, stand up."
