He is the One Who sent down this Book to you. There are two kinds of versus in this book: those [the majority of the versus] which are straight forward (and precise in meaning:) they are the essence of the Book. The remainder [few verses] are ambiguous. Those who have doubts in their hearts always go after the laters and try to interpret them arbitrarily and create mischief. In fact nobody except God knows their real meaning!17.Those who have faith, on the other hand, say: “We accept these versus [though we do not know their meaning yet] to be all words of God.”
