Which is the correct saying: "The astrologers have lied, even if they spoke the truth," or "The astrologers have lied, even if they happened to be right," and is it a Hadith or a saying?

The phrase "The astrologers have lied, even if they spoke the truth" is not a prophetic hadith, but its meaning is sound. It has been narrated in a hadith that the devils eavesdrop from the heavens and add a hundred lies to what they hear, so the soothsayer is believed because of the one true word he uttered. And whoever asks a diviner, his prayers will not be accepted for forty nights. The science of astrology is forbidden by the Qur'an, the Sunnah, and the consensus of the Ummah, because it relies on magic and idolatry.
