Is it permissible for his wife to take care of a non-mahram man who is paralysed?

Dear Brothers & Sisters,
As-Salaamu-Alaikum wa Rahmatullahi wa Barakatuh. (May Allah's Peace, Mercy and Blessings be upon all of you)
One of our brothers/sisters has asked this question:
What is the ruling on a woman taking care of her husband’s paternal uncle who is elderly, because of his health situation?
He is paralysed and cannot take care of himself. This means that the wife will be changing his diapers and clothes, and looking after him in all ways, because his wife is also elderly and sick, and she cannot look after him, and all his relatives are also elderly.
(There may be some grammatical and spelling errors in the above statement. The forum does not change anything from questions, comments and statements received from our readers for circulation in confidentiality.)

Answer:

Praise be to Allah.

If this old man does not have anyone such as a wife, sons or daughters who can take care of him, and there are no men who can take care of these matters, even in return for payment if he or whoever is looking after him can afford it, then there is nothing wrong with a non-mahram woman taking care of him, so long as she tries to avoid looking at or touching the private part. If that must be done, then it should be done using a barrier, such as gloves and the like. 

If she does these things hoping for and seeking reward with Allah, acknowledging her husband’s rights, and helping one who is sick and paralysed, then she will be rewarded, in sha Allah.

And Allah knows best.

Whatever written of Truth and benefit is only due to Allah's Assistance and Guidance, and whatever of error is of me. Allah Alone Knows Best and He is the Only Source of Strength.
Your brother and well wisher in Islam
