Clear and unclear verses

He is the One who sent down the Book, containing verses that are clear and foundational, while others are allegorical. Those with deviant hearts pursue the allegorical, seeking discord and hidden meanings. But none knows their true interpretation except Allah.

3:7He it is Who hath revealed unto thee (Muhammad) the Scripture wherein are clear revelations - they are the substance of the Book - and others (which are) allegorical. But those in whose hearts is doubt pursue, forsooth, that which is allegorical seeking (to cause) dissension by seeking to explain it. None knoweth its explanation save Allah. And those who are of sound instruction say: We believe therein; the whole is from our Lord; but only men of understanding really heed.
