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.

6:160Whoever 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.
