Does one who denies lordship believe in it in his heart, even if he denies it with his tongue?

Question:
Honorable Shaykh, may Allah grant you success, if a person denies the oneness of lordship, is it said that he only denies it outwardly and believes in it inwardly?

Answer:
We do not know about his heart, but we say that no sane person, no one who is not insane or mentally ill, and no one whose innate disposition is not corrupted, has ever denied the oneness of lordship. The innate disposition affirms the oneness of lordship.
