The ruling on one who did not stay overnight in Mina on the days of Tashriq due to an excuse, and appointed someone to stone the pillars on her behalf

Question:
Please, my brother Sa'd from Makkah. Peace be upon you. And upon you be peace. I have a question regarding my mother, may Allah be pleased with you. My mother lived through the year; on the Day of 'Arafah and the night at Muzdalifah, and on the Day of 'Id, she remained in Muzdalifah until the afternoon because she was ill; she was ill. Yes. And then we brought her to the area of al-Shisha, which is outside Mina, and she did not stay overnight in Mina for the three days. She did not stone the pillars, and her brother did it for her. And I want to see what is required of her. Okay, Honorable Shaykh Salih, he says: My mother performed Hajj on the Day of 'Arafah and stayed overnight at Muzdalifah, and she was actually tired and did not stay overnight in Mina on the days of Tashriq, and one of her sons stoned the pillars on her behalf, and she returned to her family.

Answer:
Praise be to Allah. If she was tired and ill and unable to stay overnight in Mina, then it is dropped from her. Praise be to Allah. The overnight stay is dropped from her. Praise be to Allah. And nothing is required of her because she is excused. And her appointing someone to stone the pillars is permissible and is sufficient for her, praise be to Allah. But she must perform the tawaf of farewell and the sa'y between al-Safa and al-Marwah, even if she is carried, because these are the pillars of Hajj. She must perform the tawaf, or be carried for it, and perform the sa'y, or be carried for it. Yes.
