So we know that transsexuality is caused by genetic factors, and is not an individual choice. A person with a man's body who has this gender dysphoria disoreder has the same brain structure and functions as a woman. So it is not just a choice, that a person just wakes up one day and feels like he would like to be a woman (such people do of course exist, but they are not medically classified as transsexuals and this thread does not concern them as that is obviously haram), but it is, essentially "being born in the wrong body". So what is Islams stance on this? Is a transsexual Muslim considered the gender his/her "body" is, or the the gender his/her "brain" or mind is? Are sex change operations permissible for transsexuals? With evidence from Quran/hadith/scholars please.
