He did ‘Umrah and Hajj in the same year, but on behalf of different people

Praise be to Allah.

Both Hajj and ‘Umrah are separate rituals, and the Prophet (peace and blessings of Allaah be upon him) explained how to do them as qiraan, ifraad and tamattu’. So if a person wants to enter ihraam for ‘Umrah on behalf of his mother, for example, then after exiting ihraam of ‘Umrah he wants to enter ihraam for Hajj on behalf of his father, or vice versa, he may do that. If he enters ihraam for one of them on behalf of himself, then exits ihraam and enters it for the other on behalf of his father, for example, that is permissible, because actions are judged by intentions, and each person will have that which he intended.
