I have a Dua in mind which I had for very long time, I want to know whether it is shirk or not, or whether this Dua can be answered in Paradise or not even there, because I know that there are some Duas which are not even answered in Heaven, like for example the Dha for returning to the world, that it is clearly haram even when you get in Heaven. And I need a site where a Islamic scholar can give the right answer to the question I have.

So, do you know if there is such site for asking this type of questions?
