It is narrated from Hazrat Hudhaifa (may Allah be pleased with him) that two monks from Najran, Aqib and Sayyid, came to the Messenger of Allah (peace and blessings be upon him) and said: "Send with us a trustworthy person." The Prophet (peace and blessings be upon him) said: "I will certainly send with you a completely trustworthy man." So the companions of the Prophet (peace and blessings be upon him) began to wait for this matter. The Prophet (peace and blessings be upon him) said: "O Abu Ubaidah bin Al-Jarrah! Stand up." Thus, the Prophet (peace and blessings be upon him) sent him with them.
