To perform Hajj on behalf of old people who cannot

Q 1: some people take money (between 3,000 and 4,000 saudi Riyals) to perform Hajj on behalf of another person, either because of illness or death of the person on whose behalf the Hajj is to be performed. The family of the person for whom a proxy Hajj is requested pays a sum of money to someone else to discharge this obligation on the part of their relative. (Part No. 11; Page No. 70) The person performing the Hajj spends the usual sum on the Hajj expenses, such as buying the Hady (sacrificial animal offered by pilgrims) and other expenses, and takes the rest for themselves to pay their personal expenses, such as to buy provisions and suchlike. Is this correct? Is it permissible for a woman to perform such a Hajj? Also, should pilgrims offer Salat-ul-‘Eid-ul-Adha (the Prayer for the Festival of the Sacrifice)?

A: It is permissible for someone to give another person a sum of money to perform Hajj on their behalf, either because they are unable to perform Hajj for themselves or for a deceased person, if the deputized person has already performed Hajj for themselves. The deputy is allowed to spend from this money on performing Hajj on behalf of the required person and keep the remainder; but if the proxy is given the money to perform Hajj with it and return the remainder, then they should spend from it on the expenses needed for Hajj on behalf of the required person and give back the remainder. As for Salat-ul-‘Eid-ul-Adha, pilgrims are not required to perform it, but anyone of them who performs it with the people will be rewarded.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
