The Book on Salutations and Greetings (Kitab As-Salam)
Muslim :: Book 26 : Hadith 5535
'A'isha reported: I said: Allah's Messenger, the kahins used to tell us about things (unseen) and we found them to be true. Thereupon he said: That is a word pertaining to truth which a jinn snatches and throws into the ear of his friend, and makes an addition of one hundred lies to it.
