The ruling on one who performed Hajj and did not sacrifice on his own behalf

The question: She also has another question, asking: What is the ruling on one who performed Hajj and did not sacrifice specifically for himself, but slaughtered the hady in Makkah on the Day of Sacrifice, or on the days of Tashriq, which is more correct?
The answer: The answer to this has already been given, and there is no harm in that. The udhiyah is not obligatory. If one performs Hajj and pays the fidyah with the known hady and does not sacrifice, there is nothing wrong with it.
