Is it permissible to perform Hajj on behalf of a deceased person using their money?

Question:
The questioner says: A woman died and left behind money to perform Hajj with. Do we perform Hajj for her or not? I mean, with this money?

Answer:
If she made a will, if she had not performed the Hajj of Islam. If she had not performed the Hajj of Islam, it is obligatory that someone be appointed to perform Hajj on her behalf, and the costs of Hajj are paid from the money she left behind after her death, because this is an obligation upon her. As for if she had already performed the Hajj of Islam and made a will that this money be used to perform Hajj on her behalf, then she has no right to bequeath more than one-third. She, she has no right to bequeath more than one-third. So if one-third of the money she left behind covers the full cost of Hajj, then it is obligatory to perform Hajj on her behalf and to carry out her will. But if the one-third is less than the cost of Hajj, then the Hajj is not carried out except with the consent of the heirs. If the heirs consent to it, there is no harm. Yes.
