Some people asked Allah's Messenger (ﷺ) about the fore-tellers He said. ' They are nothing" They said, 'O Allah's Messenger (ﷺ)! Sometimes they tell us of a thing which turns out to be true." Allah's Messenger (ﷺ) said, "A Jinn snatches that true word and pours it Into the ear of his friend (the fore-teller) (as one puts something into a bottle) The foreteller then mixes with that word one hundred lies."
Sahih al-Bukhari Book 76, Hadith 76
← Previous Hadith The Prophet (ﷺ) forbade the utilization of the price of a dog, the earnings of prostitute and the earnings of a foreteller.

Sahih al-Bukhari Book 76, Hadith 75 Next Hadith → A man called Labid bin al-A'sam from the tribe of Bani Zaraiq worked magic on Allah's Messenger (ﷺ) till Allah's Messenger (ﷺ) started imagining that he had done a thing that he had not really done. One day or one night he was with us, he invoked Allah and invoked for a long period, and then said, "O `Aisha! Do you know that Allah has instructed me concerning the matter I have asked him about? Two men came to me and one of them sat near my head and the other near my feet. One of them said to his companion, "What is the disease of this man?" The other replied, "He is under the effect of magic.' The first one asked, 'Who has worked the magic on him?' The other replied, "Labid bin Al-A'sam.' The first one asked, 'What material did he use?' The other replied, 'A comb and the hairs stuck to it and the skin of pollen of a male date palm.' The first one asked, 'Where is that?' The other replied, '(That is) in the well of Dharwan;' " So Allah's Messenger (ﷺ) along with some of his companions went there and came back saying, "O `Aisha, the color of its water is like the infusion of Henna leaves. The tops of the date-palm trees near it are like the heads of the devils." I asked. "O Allah's Messenger (ﷺ)? Why did you not show it (to the people)?" He said, "Since Allah cured me, I disliked to let evil spread among the people." Then he ordered that the well be filled up with earth.
