A: If the situation is as you described, it is permissible for you to perform ‘Umrah and Hajj on behalf of your mother, as the Messenger of Allah (peace be upon him) gave permission for people to perform Hajj on behalf of old people who cannot perform it due to old age and frailty.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
