IN THE NAME OF GOD, THE MOST GRACIOUS, THE DISPENSER OF GRACE[24:39]
But as for those who are bent on denying the truth, their [good] deeds are like a mirage in the desert, which the thirsty supposes to be water – until, when he approaches it, he finds that it was nothing: instead, he finds [that] God [has always been present] with him, and [that] He will pay him his account in full – for God is swift in reckoning!

* v.39 : I.e., he is bound to realize on Judgment Day that all his supposedly “good” deeds have been rendered worthless by his deliberate refusal to listen to the voice of truth (Zamakhsharī and Rāzī).
