Is it permissible to go to beaches where there is nakedness and free mixing?
Question

                In Egypt, people go to Alexandria to spend the summer there. On the beaches there are thousands of women who are virtually naked, and men mix freely with women. I am a man with a beard; is it permissible for me to go there and sit by the sea, or not?
Praise be to Allah.If the situation is as described, it is not
      permissible for a Muslim to go to these places, for fear of fitnah
      (temptation) and so as to avoid the places where it is to be found – unless he is one of those who are able to remove the evil things that are there, because they have the authority and the knowledge of sharee’ah, and are able to enjoin what is good and forbid what is evil.
