A family performed 'Umrah with a child who was nine years old, and during the sa'y (walking between al-Safa and al-Marwah) the child fell asleep, so they did not complete the sa'y with him?

Question:
He says: Honorable Shaykh, may Allah grant you success. A family went out for 'Umrah and put a child with them into the state of ihram (the consecrated state of pilgrimage) who was nine years old. During the sa'y, the child fell asleep, so they put him in a place to sleep, and they did not complete the sa'y with him, nor did they shorten his hair. They returned to Riyadh, and two months have passed since then. What is required of them?

Answer:
They must renew the ihram for the child, because he is still a Muslim, and they must return with him to complete his 'Umrah. Yes.
