Even in the verses that deal with legislation, we find signs that it could not have come from anyone other than Allah. We find that as long as mankind has been walking on the face of the Earth, we have never been able to come up with legislation that’s equivalent to that which is in the Quran. This holds true in terms of ease of application in all times and situations, the wisdom behind it and in terms of justice.
Think about this for a minute and the truth behind what was just mentioned. Can you think of one legislation that mankind has ever come up with that was not only applicable in some situations, in some places, at some points in time and wasn’t free from having many loop holes in it? Of course you can’t!
