Often, questions appear which are asking about God's wisdom behind allowing or forbidding certain things. While I'm sure there's some fair degree of philosophical study and debate on these, I don't see that such questions are really suitable for this site: Without explicit authoritative proof (e.g. an ayah or hadith explaining exactly the reason), such questions are typically not answerable except with speculation and opinion.
While such questions might be useful if they're scoped to a particular perspective ("Does such-and-such school explain why God does so-and-so?"), even then they would still run the risk of being a useless negative.
Do such questions have any place on this site at all? Is there any way to make them constructive, or should they just be closed on sight?
