The obligation of Hajj on one who spent his money on building a dwelling

Question:
And from the one who compiled the commentary, my father owned a sum of money to perform Hajj with, after the heat, but we were in need of building materials to construct a house, so he built a valley, I set up some seating, and no money remained for him to perform Hajj with. So, is there any obligation on him for that?

Answer:
If the dwelling is needed for residence, it is among the necessities, and your father is considered unable to perform Hajj, so it is not obligatory for him to perform Hajj. Allah the Exalted said: And the ability is to find the provisions and mount that will take him there, in addition to his basic needs, and among his basic needs is securing a dwelling. So if he has no dwelling and spent this money on preparing the necessary dwelling for him, he is unable to perform Hajj. But if you perform Hajj on his behalf as a form of kindness to him and precaution for him, you will be rewarded, if Allah wills, and this will benefit you, by the permission of Allah. As for the obligation, this is what is not required. Yes, and Allah the Exalted knows best. Peace and blessings be upon our Prophet Muhammad (peace and blessings be upon him).
