the qur'an possesses revelation and exegesis

we shall discuss the word, exegesis, ta'wil, in relation to three qur'anic verses. firstly, in the verses concerning the implicit mutashabih and the explicit verses: But those in whose hearts is doubt pursue, in truth, that which is allegorical talking dissension by seeking to explain it. none knows its explanation except god. [iii:7]
secondly, the verses, In truth we have brought them a scripture which we expound with knowledge, a guidance and a mercy for a people who believe. do they await anything but the fulfilment of it.
(here the word ta'wil is used connoting the appearance or clarification of meaning). On the day when the fulfilment of it comes, those who are forgetful of it will say: the messenger of our lord brought the truth [vii:52-53].
thirdly, the verse, And this Qur'an is not such as could ever be invented ... but they denied that, the knowledge of which they could not encompass and the interpretation (ta'wil) of which had not yet come to them. Even so it was that those before them deny. Then see what was the consequence in the wrongdoers. [x:37-39].
in conclusion, we should note that the word exegesis ta'wil comes from the word awl, meaning a return. as such, ta'wil indicates that particular meaning towards which the verse is directed. The meaning of revelation tanzil, as opposed to ta'wil, is clear or according to the obvious meaning of the words as they were revealed.
