I am wondering why the Quran only states what the punishment is for unmarried fornicators, but does not mention the stoning of adulterers. This which seems to be a much more serious crime with a much more severe punishment.
Edit: Apparently I'm wrong that the Quran doesn't mention a punishment for adulterers and it would seem that the same punishment, lashing, applies to both unmarried and married individuals. So my question would be why is the stoning not mentioned in the Quran, but the lashing is?
