Musannaf Ibn Abi Shaybah 39795 — Reports on the people of Najran

It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) that two bishops of Najran, al-Aqib and al-Sayyid, came to the Messenger of Allah (peace and blessings be upon him) and said: "Send a truly trustworthy man with us." He (peace and blessings be upon him) said: "I shall most certainly send with you a man of complete trustworthiness." So his (peace and blessings be upon him) Companions began waiting eagerly for this matter. He (peace and blessings be upon him) said: "O Abu Ubaydah bin al-Jarrah! Stand up." So he (peace and blessings be upon him) sent him with them.
