If the one performing tamattu' finishes his 'Umrah, is everything permissible for him?

Question:
May Allah reward you. The questioner says: A person intended to perform Hajj this year and wants to perform 'Umrah in the months of Hajj, in the month of Shawwal. So, when he returns from the 'Umrah, does he have to refrain from cutting his hair and nails and remain in the state of a person in ihram? Or does he come out of the ihram of the 'Umrah? Or, when he comes out of the ihram of the 'Umrah, is everything permissible for him until the time for entering the ihram for Hajj arrives?

Answer:
It is the last option. If he goes and performs the 'Umrah, completes it, and shortens his hair, then everything that was forbidden by the ihram becomes permissible for him. Everything that was forbidden to him by the ihram becomes permissible: he may have intercourse with his wife, he may get married, he may shave his hair, and he may cut his nails, because he is in a state of permissibility, having come out of the ihram. Then, when the time for Hajj comes, he enters the ihram for Hajj and becomes a person performing tamattu'. Yes.
