Is this narration authentic: "I have come to love falsehood, and hate truth, and believe Jews and Christians, and pray without ablution, and I possess on earth what God does not possess in heaven," and what is its interpretation?

This story has no chain of narration or origin. It is likely fabricated to highlight Ali's virtue and understanding, and to portray Umar as hasty in shedding blood. However, the meaning of the words in the question is sound, such as interpreting the disliked truth as death, and the affirmation of the claims of the Jews and Christians mentioned in the Quran.
