What is required of a disabled person who will perform 'Umrah and wears a special garment on his leg that is difficult to remove?

Question:
Honorable Shaykh, may Allah grant you success, this person says that he is disabled, with a disability in one of his legs. He wears a device inside a special garment for the device, from the top of the lock down to the knee, and he wears a boot. He wants to perform 'Umrah, and removing this is a hardship for him, and he goes down often in removing it. So is it permissible for him to perform 'Umrah in this garment on his thigh and legs, or does he owe something?

Answer:
Yes, he performs 'Umrah and performs Hajj in the garment that he is compelled to wear, but he pays the fidyah (ransom payment) for the hardship by feeding six poor people, or slaughtering a sheep, or fasting for three days. Fasting is permissible anywhere, but the feeding or the sacrifice must be in Makkah. Yes.
