Performing Hajj or purchasing a piece of land to build a house
A:
You are not required to perform Hajj unless you possess the financial means which exceed your needs and those of the family which you support in terms of food, clothing and housing. This is based on the Saying of Allah (Exalted be He):
And Hajj (pilgrimage to Makkah) to the House (Ka‘bah) is a duty that mankind owes to Allâh, for those who are able to undertake the journey.
The ability to undertake the journey means sufficient provision and a means of transportation as available in one's time. Your father is not required to perform Hajj if he falls short of possessing the necessary financial means. All praise be to Allah. (Part No. 10; Page No. 15) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
