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

                What is the ruling on one who travels for Hajj, and he intends his ‘Umrah to be on behalf of his mother and his Hajj on behalf of his father, then the next year he does it the other way round, with his Hajj on behalf of his mother and his ‘Umrah on behalf of his father. Is that permissible or not?
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.
