It is narrated from Hazrat Usama (may Allah be pleased with him) that once a Bedouin came to the service of the Holy Prophet (peace and blessings be upon him) and asked the Holy Prophet (peace and blessings be upon him): "O Messenger of Allah! Can we seek medical treatment?" The Holy Prophet (peace and blessings be upon him) replied: "Yes! Do seek treatment, for Allah has not created any disease without also creating its cure. Whoever knows it, knows it, and whoever remains unaware, remains unaware." He then asked: "O Messenger of Allah (peace and blessings be upon him)! Who is the best among people?" The Holy Prophet (peace and blessings be upon him) replied: "The one whose character is the best."
