The ruling on performing Hajj on behalf of one’s mother while she is alive

Question:
May Allah bless you. This questioner, Sultan al-Otaibi, asks and says: My mother was unable to perform Hajj, and she is fifty-five years old. She was unable to perform Hajj. Is it permissible for us to perform Hajj on her behalf, or for the son or brother to do so, using her money? Please inform us. May Allah reward you with good.

Answer:
If the mother is alive and physically capable of performing Hajj herself, it is obligatory for her to perform the Hajj of Islam, provided she has the money and a mahram (a relative one may not marry) available. However, if she is dead, or if she is alive but unable to perform Hajj herself due to a permanent inability caused by a chronic illness, then she appoints someone to perform Hajj on her behalf. You, or one of your brothers, or any Muslim, may perform Hajj on her behalf, because she has become unable to do so. Therefore, it is permissible for someone to act as her proxy in Hajj. In fact, it is obligatory for her to appoint someone to perform Hajj on her behalf and pay his expenses if he needs them, because this is the Hajj of Islam. Yes.
