6:39Those who reject Our revelations are deaf and dumb, in total darkness. Whomever God wills, He leaves astray; and whomever He wills, He sets on a straight path.

6:70So leave alone those who take their religion for play and pastime, and whom the worldly life has deceived. But remind with it, lest a soul becomes damned on account of what it has earned. It has no helper or intercessor besides God. Even if it offers every equivalent, none will be accepted from it. These are the ones who are delivered to perdition by their actions. They will have a drink of scalding water, and a painful punishment, because they used to disbelieve.

6:91They do not value God as He should be valued, when they say, “God did not reveal anything to any human being.” Say, “Who revealed the Scripture which Moses brought—a light and guidance for humanity?” You put it on scrolls, displaying them, yet concealing much. And you were taught what you did not know—neither you, nor your ancestors. Say, “God;” then leave them toying away in their speculation.

6:110And We turn away their hearts and their visions, as they refused to believe in it the first time, and We leave them blundering in their rebellion.

6:112Likewise, We have assigned for every prophet an enemy—human and jinn devils—inspiring one another with fancy words in order to deceive. But had your Lord willed, they would not have done it. So leave them to their fabrications.

6:137Likewise, their idols entice many idolaters to kill their children, in order to lead them to their ruin, and confuse them in their religion. Had God willed, they would not have done it; so leave them to their fraud.
