Is Hajj valid by intention or by utterance if the intention of entering into Ihram differs from uttering it?

If you utter something unintentionally due to a slip of the tongue, it does not have an effect, for the Prophet, peace and blessings be upon him, said: "Indeed, actions are by intentions, and every person will have what he intended." The consideration is what is in the heart, and a slip of the tongue does no harm.
