A man performing Hajj on behalf of someone who has never performed Hajj

Al-Hasan said concerning a man who performs Hajj on behalf of someone who has never performed Hajj: it will suffice on his behalf.

Sa'id bin al-Musayyib said: Indeed, Allah Almighty will extend this one Hajj to cover both of them (both will receive its reward).

Al-Hasan said concerning a man who performs Hajj on behalf of another man: it is hoped that he too will receive a reward like his.
