What is the ruling on forgetting to shave the head after 'Umrah and committing some of the prohibited acts?

Question:
If a person performed 'Umrah and forgot to shorten or shave his hair, then returned to his country and committed some of the prohibited acts, including sexual intercourse, what is the ruling?

Answer:
If he forgot to shave or shorten his hair and returned to his country, he has to exchange his clothes, remove the sewn garments, and put on the ihram clothes, then shave or shorten his hair, and with this his ritual is completed. If he engaged in sexual intercourse, his 'Umrah is invalid if he engaged in sexual intercourse. If he engaged in sexual intercourse, he slaughters a sheep, if Allah wills, and his 'Umrah is valid if he engaged in sexual intercourse before shaving. He slaughters a sheep in Makkah, he slaughters a sheep in Makkah and distributes it to the poor, and his 'Umrah is completed by the permission of Allah. Yes.
