Do psychological and physical ailments (obsessive-compulsive disorder, high cholesterol, rapid heart rate) prevent marriage Islamically? Is it obligatory to inform the fiancée and her family about these ailments? How valid are the fears of the condition deteriorating after marriage? And how can one determine if these symptoms are caused by magic, an evil eye, or envy?

The defect that necessitates disclosure before marriage and establishes the option [for annulment] is the repulsive defect, one that negates the purpose of marriage, which is affection and mercy. Obsessive-compulsive disorder (OCD), if it takes strong hold of an individual, is considered one of these repulsive defects that obligates disclosure before marriage. If your OCD has not reached a repulsive level, you are not required to disclose it, and marriage is permissible for you. However, if the condition has reached a repulsive level, you must disclose it at your first meeting to avoid harm and damage. Your apprehension about your condition worsening after marriage is a symptom of OCD, and you must resist it and seek Allah's help. It is advisable to consistently perform ruqyah (definition) (Islamic exorcism/spiritual healing) and consult specialists in Quranic healing to determine the extent to which magic or the evil eye might be causing it.
