The ruling on saying: "I am a Jew or a Christian" in order to deter oneself from an action

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on a person saying that he is a Jew or a Christian or a Zoroastrian in order to deter himself from committing the action he wants to refrain from?

Answer:
The Prophet (peace and blessings be upon him) . So if he is lying, he is as he said, and otherwise he will not return to Islam safely. Therefore, it is not permissible for a person to swear by a religion other than Islam, saying, "I am a Jew if I do such and such," or "if I do not do such and such," or "I am a Christian." If he is lying, he is as he said, and if he is not lying, he will not return to Islam safely. He has committed a sin. A person should avoid these expressions. Yes.
