(117) باب قَوْلِ الرَّجُلِ لِلشَّىْءِ لَيْسَ بِشَىْءٍ وَهْوَ يَنْوِي أَنَّهُ لَيْسَ بِحَقٍّ
Narrated `Aisha:
Some people asked Allah's Messenger (ﷺ) about the fore-tellers. Allah's Messenger (ﷺ) said to them, "They are nothing (i.e., liars)." The people said, 'O Allah's Messenger (ﷺ) ! Sometimes they tell something which comes out to be true." Allah's Messenger (ﷺ) 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."
