Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: A man came to the service of the Prophet (peace and blessings of Allah be upon him). He asked: O Messenger of Allah! Which deed has the most virtue? He replied: The person who strives in the way of Allah with his life and wealth. He asked: Then which one? He said: The believer who lives in a mountain pass, worships Allah Almighty, and keeps people safe from his evil.
