It is narrated from Yahya bin Abi Kathir (may Allah have mercy on him) that a non-Arab man came to the mosque; he had let his moustache grow long and had cut his beard short. The Messenger of Allah (peace and blessings be upon him) asked him: "What prompted you to do this?" He said: "My Lord commanded me to do this." The Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty has commanded me to let my beard grow and to trim my moustache short."
