What is required of the son and his guardian if the son refuses to complete the 'Umrah after starting it?

Question:
May Allah reward you, Honorable Shaykh. A questioner says: A person put his son in the state of ihram for 'Umrah, and the son is thirteen years old. However, when he had completed three circuits of tawaf, he refused to complete the 'Umrah entirely, and then they returned to Riyadh. What is required of the son and his guardian?

Answer:
He must return; it is obligatory to return and complete the 'Umrah, because he is still in the state of ihram for 'Umrah. It is obligatory for him to return and perform the rites of 'Umrah because he is still in ihram. He must avoid the prohibitions of ihram, remove the sewn garments, and put on the ihram garments immediately. Then he goes to Makkah and performs the 'Umrah.
This matter is not a matter of playing with acts of worship. Allah (Exalted and Majestic is He) says: Since this person did not perform the rites, it is obligatory for him to return. He is still in the state of ihram. Yes.
