It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The most virtuous deed in the sight of Allah is such faith in Allah in which there is no doubt, and such striving (jihad) in which there is no dishonesty, and an accepted Hajj (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.
