He it is who has bestowed upon thee from on high this divine writ, containing messages that are clear in and by themselves - and these are the essence of the divine writ - as well as others that are allegorical.* Now those whose hearts are given to swerving from the truth go after that part of the divine writ* which has been expressed in allegory, seeking out [what is bound to create] confusion,* and seeking [to arrive at] its final meaning [in an arbitrary manner]; but none save God knows its final meaning.* Hence, those who are deeply rooted in knowledge say: "We believe in it; the whole [of the divine writ] is from our Sustainer - albeit none takes this to heart save those who are endowed with insight.
But as for those from among them who are deeply rooted in knowledge,* and the believers who believe in that which has been bestowed upon thee from on high as well as that which was bestowed from on high before thee, and those who are [especially] constant in prayer,* and spend in charity, and all who believe in God and the Last Day - these it is unto whom We shall grant a mighty reward.
