There are lots of Islamic websites. Among them, some are very excellent and of course credible. I don't think a Muslim scholar would open a website to spread lies and whims. This can be done by the enemies of Islam.

As you are a Muslim, you are not supposed to visit anti-Islamic websites which are full of propaganda, even though they try to sound credible. Those are traps for Muslims. Most regular Muslims are of weak faith, and they are their target. When oblivious Muslims visit such sites, they may start thinking "really?" due to their ignorance of own religion.

You should visit sites like:
