One common feature I've seen on most if not all Islamic Q&A sites is a slew of rulings requests (especially "Is such-and-such permissible in Islam?"-type questions)
Although such questions seem to be within the scope of "Q&A site for the Muslim community who have questions about Islam", I worry that such would be a poor fit for the StackExchange format due to differences of scholarly opinions in many areas, particularly when dealing with situations which just plain didn't exist during the time of the prophet. There often wouldn't be one answer which would be "definitively correct".
(Compare the closely-related "According to the Hanafi madh'hab, is such-and-such permissible?" which would be more likely to have a definitive answer.)
Should such questions be allowed at all? If so, what limits (if any) should be upheld?
