Why does the Cyclops invite Odysseus back to the island?

In Homer's epic, "The Odyssey," the Cyclops, Polyphemus, invites Odysseus back to the island as a part of a curse. After Odysseus blinds Polyphemus and escapes, the Cyclops prays to his father, Poseidon, to curse Odysseus. As part of this curse, Polyphemus sarcastically invites Odysseus back, hoping that Poseidon will make his journey home difficult and filled with hardships. This invitation is not a genuine gesture of hospitality but rather a way to ensure that Odysseus suffers further consequences for his actions.
