Volume 8, Book 73, Number 232:
Narrated ‘Aisha:
Some people asked Allah’s Apostle about the fore-tellers. Allah’s Apostle said to them, “They are
nothing (i.e., liars).” The people said, ‘O Allah’s Apostle ! Sometimes they tell something which comes
out to be true.” Allah’s Apostle said, “That word which comes to be true is what a jinx snatches away
by stealing and then pours it in the ear of his fore-teller with a sound similar to the cackle of a hen,
and then they add to it one-hundred lies.”
