Q: My father died on Friday, 11/12/1420 A.H. His brother, who is around 60 years old, now lives with my mother, brother, and sister in one house. I would like to clarify my uncle’s situation.He is an ordinary man, he does not like to interfere in other people’s business, and he does not have the ability to argue with people or keep up with them. However, he is not an idiot or insane; he is a normal person.It is worth mentioning that he was previously married, but his marriage was not fated to continue, and his wife asked for Khul‘ (divorce initiated by a wife for a consideration). When she went to the judge and explained the matter to him, it became evident to the judge that my uncle has no sexual desire at all; he is blind to women’s charms. So the judge had no choice but to grant his wife Khul‘ without an ‘Iddah (woman’s prescribed waiting period after divorce or widowhood). This Khul‘ was not the beginning of this problem; he has been known to have this condition for many years.The question is: My mother now is in her ‘Iddah period following my father’s death (may Allah be merciful to him), is it permissible for her to treat my uncle in the prescribed way of treating men who have no interest in or desire for women, a child, or even a Mahram (unmarriageable male relative), or should he be considered an Ajnaby (a man other than a husband or unmarriageable male relatives) to her in the very sense of the word? (Part No. 17; Page No. 196) There is no possibility of Khulwah (being alone with a member of the opposite sex) here at all, as some of my mother’s children are staying with her. Also my wife, should she treat him in the same way my mother does?
