Delaying Ones Hajj

Q: Hajj-1: Will a Person be sinful for delaying his Hajj?

Answer: If Hajj is Fardh (obligatory) for a person and he does not perform Hajj at the first opportunity, he will be guilty of a serious sin and is liable for punishment. However, if he does perform the Hajj thereafter, he will be absolved of the sin. And will no longer remain a sinner. And Allaah knows best what is most correct.
