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