Q: A non muslim person has made a firm intention to accept islam Alhamdulillah. The challenge is that this person has been undergoing a sex change to such an extent that all features are feminine including breasts and voice. The only procedure this person needs to undergo is the sex organ change.
- Should this person be advised to reverse the process or should this person be allowed to go ahead with the sex change. (If told not to there is a fear that he will turn away from Islam).
 - Should the above be done after this person recites the shahadah or before?
 - At this stage (before the sex organ change)is this person regarded as a male or a female  considering all apparent features are feminine?
 - Who should be allowed to interact with this person a muslim male or a female?
 - What other advice can mufti sahib give regarding this matter?
 
A detailed response on the above matters with shar'ee citations will be greatly appreciated.
