It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the people of Yemen came to the Messenger of Allah, peace and blessings be upon him, and said: "Send us a man who will teach us the religion." The Prophet, peace and blessings be upon him, took the hand of Sayyiduna Abu Ubaidah bin Jarrah, may Allah be pleased with him, and sent him with them and said: "He is the trustworthy one of this Ummah."
