مناسك حج - مكارم شيرازى، ناصر - الصفحة ٢٠ - Conditions of Necessity of Hajj
Article ٢- Hajj is obligatory for a person when he has enough money for buying a house, if they needs are not being sufficed without owning a house; but if the person can live in a rental house or Waqf( inalienable religious endowment )house or like them, then he is able or performing Hajj by having that kind of house.
Article ٣- Whenever a person does not have enough money for going to Mecca, but another person bestows him or gives him the money for performing Hajj and also this person pays the costs of his family during this pilgrimage then Hajj is obligatory for him, even he has debts or has not a job or business for paying the costs of living, and accepting such a gift is obligatory; unless that person puts him under severe moral obligation by accepting this gift or there is a loss or intolerable hardness in accepting that, and performing this Hajj is like performing the obligatory Hajj.
