What is the ruling on delaying the duty of Pilgrimage for reasons, like "I spare for the education of my child, my child will marry, etc."?
Such reasons are unacceptable. Everyone has to spend for the education of their children, that is a duty for sure. However, the duty of Hajj is of first priority. A person should fulfill this duty as soon as he/she finds the opportunity. Do we ever say: “Let my child marry and I will drink soup”?
Spending for education, marriage, etc. and the obligatory worship of Hajj are different duties. You should fulfill the duty of Hajj whenever you have the opportunity. Otherwise, the person would be responsible for this behavior when he/she loses the opportunity.
