He it is Who has sent down to thee the Book: In it are verses basic or fundamental (of established meaning); they are the foundation of the Book: others are allegorical. But those in whose hearts is perversity follow the part thereof that is allegorical, seeking discord, and searching for its hidden meanings, but no one knows its hidden meanings except Allah. And those who are firmly grounded in knowledge say: "We believe in the Book; the whole of it is from our Lord:" and none will grasp the Message except men of understanding.

但他们中学问渊博的，确信正道的----确信降示你的经典，和在你之前所降示的经典----和谨守拜功的，完纳天课的，和确信真主与末日的人，这等人， 我将赏赐他们重大的报酬。

他降示你这部经典，其中有许多明确的节文，是全经的基本；还有别的许多隐微的节文。心存邪念的人，遵从隐微的节文，企图淆惑人心，探求经义的究竟。只有真主和学问文精通的人才知道经义的究竟。他们说：“我们已确信它，明确的和隐微的，都是从我们的主那里降示的。惟有理智的人，才会觉悟。
