He it is Who has revealed the Book to you; some of its verses are decisive, they are the basis of the Book, and others are allegorical; then as for those in whose hearts there is perversity they follow the part of it which is allegorical, seeking to mislead and seeking to give it (their own) interpretation. but none knows its interpretation except Allah, and those who are firmly rooted in knowledge say: We believe in it, it is all from our Lord; and none do mind except those having understanding.

Most surely in the creation of the heavens and the earth and the alternation of the night and the day there are signs for men who understand.

(It is) a Book We have revealed to you abounding in good that they may ponder over its verses, and that those endowed with understanding may be mindful.
