Entering ihram for 'Umrah from the plane: Is it permissible to go to the miqat and repeat the 'Umrah?

The questioner : In her first question, she says: Shaykh, they entered ihram for 'Umrah from the miqat while on the plane, and they want to perform a second 'Umrah.

The Shaykh : Allah, the Most Merciful, the Most Compassionate. Praise be to Allah, Lord of the worlds. May Allah send prayers and blessings upon our Prophet Muhammad, his family, his Companions, and those who follow them in excellence until the Day of Judgment. I say: They do not perform a second 'Umrah unless they return to their home and then start another journey. We do not flee to al-Tan'im; we have a house in Makkah.
This is because performing a second 'Umrah in a single journey is not the way of the Prophet (peace and blessings be upon him) nor the way of his Companions. It is known that if it had been prescribed, the Prophet (peace and blessings be upon him) would have prescribed it for his Ummah, either by his saying, his doing, or his approval. But the Messenger (peace and blessings be upon him) did not prescribe it for his Ummah, and the Companions (may Allah be pleased with them) did not do it. They were more eager for good than we are, and more desirous of it. If it had been good, they would have preceded us to it. Repeated 'Umrah was not reported except in one specific case with a particular cause, which is the case of 'A'ishah (may Allah be pleased with her). 'A'ishah (may Allah be pleased with her) entered ihram for 'Umrah during the Farewell Pilgrimage, and she started menstruating on the way before reaching Makkah. The Prophet (peace and blessings be upon him) ordered her to make her 'Umrah into Hajj, so she became a qarin (one combining 'Umrah and Hajj). She did so. When the Hajj was finished, she insisted on the Prophet (peace and blessings be upon him) to let her perform an independent 'Umrah. He permitted it and ordered her brother 'Abd al-Rahman ibn Abi Bakr to take her out to al-Tan'im. She entered ihram from that place, and her brother 'Abd al-Rahman was with her, but he did not perform 'Umrah. If it had been prescribed, he would have performed it, because he went out to al-Tan'im. But he did not perform it because he knew that this was not the established, prescribed practice. And these people who seek good multiply their tawaf.
And in tawaf there is good and blessing, because tawaf is prescribed for 'Umrah, Hajj, and other occasions. But repeating 'Umrah is not from the Sunnah.
So much so that some scholars said: I do not know whether these people are rewarded or sinned against, meaning, do they receive reward or do they commit sin? Because they did what was not prescribed in the time of the Messenger (peace and blessings be upon him). My advice to this questioner and to others is not to repeat 'Umrah, neither in Ramadan nor at any other time, if it is possible for them to return to their home.
