Will I be sinful if I enter a website with the inscription: "If you divorced your wife like me... enter here" unintentionally, but rather for the purpose of perusal and searching for fatwas?

Your accessing this page does not result in divorce, nor does anything become binding upon you due to it. We advise you to beware of waswasah (whispers/obsessive thoughts) concerning divorce or anything else, for it is evil and a trial. Turning away from it is the best remedy.
