My mother did not manage to complete the rounds of Sa`y

Q: My parents went to Makkah Al-Mukarramah (Makkah, the Honored) to perform Tamattu` Hajj (`Umrah during the months of Hajj followed by Hajj in the same year with a break in between). They performed `Umrah (lesser pilgrimage) very easily - Al-hamdu lillah (All praise is due to Allah). However, during the performance of the rituals of Hajj, specifically Sa`y (going between Safa and Marwah during Hajj and `Umrah), my mother did not manage to complete its rounds. She only performed five rounds and felt completely exhausted during the fifth that she could not go on. She has been suffering from dermatological problems for more than ten years, and the complications worsen in hot weather and crowded places. My father and the group left her in one part of Mas`a (the place where pilgrims go between Safa and Marwah), and completed their rounds. After that they took her and tried to find a wheelchair for her, but they did not find any. When they came back to their tent, they asked about the ruling on what had happened. Someone told them that she had to complete her Sa`y before leaving Makkah Al-Mukarramah. When they went to perform Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah), my mother, my stepmother, and others in the group completed their Tawaf, but my father did not manage to complete the first round because of suffering from sunstroke (Part No. 10; Page No. 267) after his return from Sa`y as a result of which he was taken to a hospital in Makkah. He, thus, did not manage to complete Tawaf and the group took him away from the crowd outside the Masjid (mosque) in order to complete their Tawaf. After finishing their Tawaf, they came back to take him and left Makkah heading for Madinah and then returned home to Hafr Al-Batin. There was a woman among the group who was possessed by Jinn (creatures created from fire) after performing `Umrah easily and comfortably.After performing `Umrah, she was possessed by Jinn and did not manage to complete the rituals of Hajj. This made the group hasten to leave Makkah Al-Mukarramah. That woman had gone to Makkah Al-Mukarramah to perform Hajj for the first time.I hope Your Eminence will clarify the ruling on the validity of my parents' Hajj and illustrate what they should do and when.Is the Hajj of this Jinn-possessed woman valid or not? Benefit us, may Allah reward you with the best!
