Hajj-e-Badal

Delaying Hajj until one is unable to perform it due to old age

Q: A person had the means of performing hajj, but didn't do so. When he becomes old he becomes more practising and regrets not having performed hajj when he was young. Now he is too old, weak and sick to perform hajj. Will he be punished in the hereafter for not having performed hajj when he was young and able to do so, or will he be forgiven due to his regret?
