The ruling on one who is prevented from completing 'Umrah if he made a condition upon entering ihram

Question:
The questioner says, may Allah protect you: What is the ruling for one who went to perform 'Umrah but was prevented by an obstacle before reaching Makkah, yet when he entered the state of ihram from the miqat, he made a condition at the time of his intention? Is he required to offer a sacrifice upon exiting the state of ihram?

Answer:
If he enters ihram and makes the condition, “May a preventer prevent me, then my place of exiting ihram is where I am prevented,” and a preventer does prevent him, then he owes nothing. The Prophet (peace and blessings be upon him) said to his cousin’s daughter, who said, “I intend to perform Hajj, but I find myself ill, meaning I have a fever.” He said: If he says this upon entering ihram and is prevented by a preventer, then he owes nothing. Yes.
