Do ye bury this wicked boy in the deep with rocks. Fire did not burn him; the weapons did not hurt him; the serpents could not bite him; nor the withering blast, poison, and the magical incantations bring about his destruction. He baffled the illusions (of Samvara), fell unhurt from the loftiest mountains, foiled the elephants of the skies. He is a wicked boy and his life is a perpetual source of miseries. Let him be buried down with rocks into the deep.

In plain words: Hiranyakashipu orders the demons to pin the boy under the sea with rocks. He lists every attack Prahlada has survived: fire, weapons, snakes, poison, deadly wind, magic, falls from mountains and the elephants that guard the sky. He calls his son a constant source of misery.
