The husband having intercourse with his wife, who is in the state of ihram for 'Umrah alone, before the tawaf

Question:
The question is often posed to the honorable scholars in the cabins. One of the sheikhs asks about the wives of residents in the Kingdom when they come from their country in the state of ihram for Hajj, performing it as ifrad. Then their husband meets them at the airport while they are in ihram, and it may happen that he has intercourse with them before the tawaf and sa'y. What is the ruling in that?

Answer:
He has invalidated her ihram. Is it not permissible for him to have intercourse with her while she is in ihram? It is forbidden for him to do so. Yes.
