It is He who has sent down the Book to you. Some of its verses are clear and precise in meaning, they are the basis of the Book, while others are allegorical. Those with deviation in their hearts pursue the allegorical, so as to create dissension by seeking to explain it: but no one knows its meaning except God. Those who are firmly grounded in knowledge say, "We believe in it: it is all from our Lord." But only the wise take heed.
