He it is who has revealed to you the Book, in which there are some verses that are Basic (decisive, or of established meaning) they are the mother (foundation) of the Book; and others are allegorical. But as for those in whose heart is perversity, they follow what is allegorical seeking discord, craving for (their own) interpretation of it; but none know the interpretation of it except Allah. And those who are well grounded in knowledge say, "We believe in it; it is all from our Lord"; but none will grasp the message save those who possess understanding. (Or: but none know the interpretation of it except Allah and those who are well grounded in knowledge. Say: "We believe in it, it is all from our Lord, but none will grasp the message save those who possess understanding.)
