6:4Not one of their Lord’s signs comes to them, but they turn away from it.

6:31Losers are those who deny the encounter with God. Then, when the Hour comes upon them suddenly, they will say, “Alas for us, how we have neglected it.” And they will carry their burdens on their backs—evil is what they carry.

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.

6:124When a sign comes to them, they say, “We will not believe unless we are given the like of what was given to God’s messengers.” God knows best where to place His message. Humiliation from God and severe torment will afflict the criminals for their scheming.

6:160Whoever comes up with a good deed will have ten times its like; and whoever comes up with an evil deed will be repaid only with its equivalent—they will not be wronged.
