The Prophet (may Allah's peace and blessings be upon him) was asked who the best of men is. He stated that it is the man who strives in the cause of Allah with his wealth and his life. When asked about the next best man, the Prophet (may Allah's peace and blessings be upon him) said: "It is the man who isolates himself in a valley to worship Allah and let people be safe from his evil." This means that the man is busy worshiping Allah, keeping away from people, and preventing his evil from coming to them.
