Hadith 7000
Sayyiduna Hudhaifah (may Allah be pleased with him) narrates: Two priests (or monks) from Najran, Aqib and Saeed, came to the service of the Prophet Muhammad (peace be upon him). They said: Send with us a trustworthy person who is truly trustworthy. So the Prophet Muhammad (peace be upon him) said: I will send with you a trustworthy person. The companions of the Prophet Muhammad (peace be upon him) became attentive to this. Then the Prophet Muhammad (peace be upon him) said: O Abu Ubaidah bin Jarrah, stand up. So the Prophet Muhammad (peace be upon him) sent him with those people.
