6:25Among them are those who listen to you; but We place covers over their hearts, to prevent them from understanding it, and heaviness in their ears. Even if they see every sign, they will not believe in it. Until, when they come to you, to argue with you, those who disbelieve will say, “These are nothing but myths of the ancients.”

6:28What they used to conceal before will become clear to them. And even if they were sent back, they would revert to what they were forbidden. They are liars.

6:52And do not drive away those who call upon their Lord, morning and evening, seeking His attention. You are not accountable for them in any way, nor are they accountable for you in any way. If you drive them away, you would be one of the unjust.

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.

6:109They swear by God, with their most solemn oaths, that if a miracle were to come to them, they would believe in it. Say, “The miracles are only with God.” But how do you know? Even if it did come, they still would not believe.

6:111Even if We sent down the angels to them, and the dead spoke to them, and We gathered all things before them, they still would not believe, unless God wills; but most of them are ignorant.

6:152And do not come near the property of the orphan, except with the best intentions, until he reaches maturity. And give full weight and full measure, equitably. We do not burden any soul beyond its capacity. And when you speak, be fair, even if it concerns a close relative. And fulfill your covenant with God. All this He has enjoined upon you, so that you may take heed.
