Is it permissible for one who recites over the sick to uncover the faces of women and look at them, especially those he believes are afflicted with jinn?

Question:
Wasa'il says: There is a young man I know who recites over the sick. While reciting over women, especially those he believes are afflicted with jinn, he sometimes uncovers their face and looks at it. Then he tells his companions, "This one is beautiful," or "This one is the one I want to marry," and other things he sees. When we advised him against this action, he said, "I have a fatwa from the shaykhs permitting uncovering the face in cases of necessity."

Answer:
This is a matter for consideration. If the illness is in the face, the need calls for looking at it. The doctor does not look at the face; rather, he looks at the organ where the illness is. If a woman is not available to perform what is necessary, it is obligatory to turn to her so that evil is avoided. If no woman who knows the treatment and possesses good character is available, the man may look if he knows of this, and there must be no seclusion, only to the extent of the barrier.
It is not permissible for him to say, "I looked at so-and-so, so-and-so is such and such, and so-and-so is such and such." This is not permissible for him. Rather, he looks only at the place of need for the sake of treatment. He should not say, "So-and-so is such and such, and so-and-so is such and such," either criticizing her or praising her, thereby tempting people with her, except in cases of need, such as in the context of a marriage proposal.
