Is it permissible for someone to

Q 1: my mother is an old woman; not less than one hundred years old, and so she is incapable of performing the obligatory duty of Hajj. I performed Hajj and ‘Umrah (lesser pilgrimage) on her behalf last year at her expense. Some people have said that it is not valid to perform Hajj on her behalf until after her death and that the Hajj I performed is rewardless. What is your opinion on this?

A: If your mother cannot perform them herself, due to her old age, the Hajj and ‘Umrah which you performed on her behalf are valid, provided that you had performed the Hajj and ‘Umrah that are obligatory on you first.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
