7:37Who does greater wrong than he who invents lies about God, or denies His revelations? These—their share of the decree will reach them. Until, when Our envoys come to them, to take their souls away, they will say, “Where are they whom you used to pray to besides God?” They will say, “They have abandoned us,” and they will testify against themselves that they were faithless.

7:172And when Your Lord summoned the descendants of Adam, and made them testify about themselves. “Am I not your Lord?” They said, “Yes, we testify.” Thus you cannot say on the Day of Resurrection, “We were unaware of this.”
