Hajj is an obligatory worship on every Muslim who is able to perform it. It becomes obligatory immediately on the ability to perform it. There is no option to delay it when there is ability. In fact, delaying Hajj after ability is a sinful act. A person who delays Hajj will not die as a Muslim if he dies before performing Hajj ( يقال لتارك الحج إذا مات مت إن شئت يهوديا أو نصرانيا ).

 There is no age limit in Hajj. Hajj Must be performed immediately when we are able to perform it.
