If you disbelieve - indeed, Allah is Free from need of you. And He does not approve for His servants disbelief. And if you are grateful, He approves it for you; and no bearer of burdens will bear the burden of another. Then to your Lord is your return, and He will inform you about what you used to do. Indeed, He is Knowing of that within the breasts.
And when adversity touches man, he calls upon his Lord, turning to Him [alone]; then when He bestows on him a favor from Himself, he forgets Him whom he called upon before, and he attributes to Allah equals to mislead [people] from His way. Say, "Enjoy your disbelief for a little; indeed, you are of the companions of the Fire."
Is one who is devoutly obedient during periods of the night, prostrating and standing [in prayer], fearing the Hereafter and hoping for the mercy of his Lord, [like one who does not]? Say, "Are those who know equal to those who do not know?" Only they will remember [who are] people of understanding.
