What is the ruling on the dowry — advanced and deferred — and gifts, and on the marriage contract in the presence of deceit: is it valid or void if the husband discovers that his wife concealed from him a disease that affects procreation and causes hair growth and body acne, and he has not yet consummated the marriage?

The defects that necessitate disclosure before marriage and establish the right to annulment are those that prevent intercourse or are repulsive and contagious diseases. What you mentioned about your wife's illness does not fall under these defects, and therefore, it does not establish your right to annulment. Your wife should have been truthful when asked, and the marriage contract is valid as long as it fulfills the conditions and pillars. If you wish to divorce, she is entitled to half of the agreed upon Mahr (dowry), including the jewelry (Shabaka) if it was part of the Mahr. As for gifts that are not part of the Mahr, some scholars have permitted their return if consummation has not occurred.
