Does Hajj expiate sins, including major ones?

Major sins are not expiated except through sincere repentance. What Allah has promised regarding the expiation of sins through acts of obedience applies only to minor sins, as stated in the Hadith: "The five daily prayers, and Friday prayer to Friday prayer, and Ramadan to Ramadan are expiations for what is between them, provided that major sins are avoided." Thus, Hajj does not expiate major sins; rather, they require specific repentance.
