Is a woman permitted to seek divorce and take her dower (mahr) if she discovers that her husband is impotent after two years of marriage, knowing that he concealed this matter from her despite their agreement before marriage about his epilepsy that might cause infertility?

If the husband's impotence is proven before the judge, the husband is granted a full year. If he is unable to have intercourse within this period, and the wife chooses separation, the judge separates them, and the wife is entitled to the full dowry, according to the majority of scholars. Impotence is proven by the husband's admission, or by the testimony of two witnesses, or by the wife's oath after his refusal to take an oath. The one-year period begins from the date the judge specifies it, not from the date of admission or oath. Scholars have explained that this period is set to give the husband an opportunity for treatment and to confirm that the incapacity is not a temporary or seasonal condition.
