Surah 14. Ibrahim, Ayah 11

I.e., it is to the contents of the divine message propounded to them that all seekers after truth must turn for illumination (see 7:75 and 13:43 , as well as the corresponding notes). The Qur'an dwells in many places (e.g., in {6:109-111} or 13:31 ) on the futility - moral as well as intellectual-of the demand that the divine origin of a prophetic message should be proved by tangible, extraneous means: for, a morally valid and intellectually justifiable conviction of the intrinsic truth of such a message can be gained only through "conscious insight accessible to reason" ( 12:108 ).
