It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that a man asked the Prophet (peace and blessings be upon him), "O Messenger of Allah! Which is the most virtuous deed?" The Prophet (peace and blessings be upon him) replied: "The most virtuous deed in the sight of Allah is faith in Allah in which there is no doubt, and such jihad in which there is no dishonesty, and Hajj Mabroor." Hazrat Abu Huraira (may Allah be pleased with him) says that Hajj Mabroor becomes an expiation for all the sins of that year.
