In Islam, marriage is considered a sacred and important institution. The permissibility of marriage for someone with dissociative identity disorder (formerly known as multiple personality disorder) is not explicitly addressed in Islamic texts because the understanding and recognition of mental health conditions have evolved over time.
In Islamic jurisprudence, the ability to marry is generally based on a person's mental and legal capacity to consent to marriage and fulfill the responsibilities of a spouse. If an individual with dissociative identity disorder is deemed to have the necessary mental capacity to understand and fulfill the obligations of marriage, they would be allowed to marry according to Islamic principles.
It is crucial to consider the well-being of the person with dissociative identity disorder and their potential spouse before proceeding with the marriage. Islamic teachings emphasize the importance of compassion, empathy, and understanding in dealing with individuals facing mental health challenges.
If you or someone you know is in such a situation, it is advisable to consult with a knowledgeable and compassionate Islamic scholar or a mental health professional who can provide guidance based on individual circumstances and religious principles.
