6:51And warn with it those who fear to be gathered before their Lord—they have no protector or intercessor apart from him—perhaps they will grow in piety.

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.

6:94“You have come to Us individually, just as We created you the first time, leaving behind you everything We gave you. We do not see with you your intercessors—those you claimed were your partners. The link between you is cut, and what you had asserted has failed you.”
