Does looking at a hand upon which skin taken from the thigh has been grafted become unlawful (haram)?

What is transferred from a person's thigh to their hand for treatment or cosmetic purposes is not considered 'awrah; rather, it becomes part of the hand and takes on its rulings. Therefore, it must be washed during ablution (wudu') and wiped over during dry ablution (tayammum) if it is part of the palm. Thus, whatever skin is taken from the thigh or elsewhere to cover the hand or other parts, its ruling does not separate; instead, it becomes part of the limb to which it was transferred and takes on its ruling.
