Is the one who owes a sacrificial animal in Hajj and delays it for an excuse sinful?

Question:
Fatwa number: The questioner says: I performed Hajj, and my father did as well, praise be to Allah. There was a family member among us for whom I was unable to perform the Tawaf of Ifadah, as he could not walk on his feet. I asked in the Haram, and they said you owe a sacrificial animal. However, due to my circumstances, I did not slaughter it at that time, and I left Makkah. Until now, I have not slaughtered the sacrificial animal that is obligatory for my father. Please issue a ruling for us, may Allah reward you with good.

Answer:
Answer: If the Tawaf he left was the Tawaf of Ifadah, which is the Tawaf of Hajj that the pilgrim performs after descending from Muzdalifah, then a sacrificial animal does not suffice for it. Your father must return to Makkah and perform this Tawaf, either walking or being carried. He also owes a sacrificial animal if he had intercourse with his wife after Hajj; he must slaughter it in Makkah and distribute it to the poor there. However, if what was left was the Tawaf of Farewell, which the pilgrim performs after completing the rites of Hajj and when leaving Makkah, then he owes a sacrificial animal for it, which he must slaughter in Makkah for the poor there as well. And success is from Allah.
