What is the ruling on one who performed Hajj as a mutamatti' and did not complete the sa'y of 'Umrah while ignorant?

Question:
A person from the people of the miqat entered the state of ihram for 'Umrah, meaning it was a Hajj of tamattu', but he performed seven circuits of tawaf, walked two circuits of sa'y, and did not complete the sa'y. He is a pilgrim. A person entered the state of ihram from the miqat for 'Umrah, meaning his intention was for Hajj, but he performed seven circuits of tawaf, walked two circuits of sa'y, and did not complete the sa'y because he did not know the number of circuits, or out of ignorance. He then took off his ihram clothes and put on sewn garments. After he realized his mistake, he put on the ihram clothes again and performed the sa'y without going to the miqat. What is the ruling in this case?

Answer:
Well, his work is valid. When he realizes he made a mistake, he puts on the ihram clothes again, performs seven circuits of tawaf for the 'Umrah, and performs seven circuits of sa'y for the 'Umrah. Then he shaves his head or shortens his hair, and with that his 'Umrah is complete. He does not go to the miqat because he entered the state of ihram from the miqat and he remains in his state of ihram; he is still in ihram. There is no need for him to go to the miqat because he is in ihram and still in ihram. His exiting the state of ihram by mistake does not affect his status because he was ignorant, but he must put on the ihram clothes and perform the 'Umrah as we mentioned.
