Hadith

Reported by `Aishah (RA) said: Some people asked the Messenger of Allah (peace be upon him) about soothsayers. He (peace be upon him) said, "They are of no account.'' Upon this they said to him, "O Messenger of Allah! But they sometimes make true predictions.'' Thereupon the Messenger of Allah (peace be upon him) said, "That is a word pertaining to truth which a jinn snatches (from the angels) and whispers into the ears of his friend (the soothsayers) who will then mix more than a hundred lies with it.'' [Bukhari & Muslim]
