Sahih Muslim 2228 b
'Urwa reported from 'A'isha that she said that people asked Allah's Messenger (ﷺ) about the kahins. Allah's Messenger (ﷺ) said to them:
It is nothing (i. e. it is a mere superstition). They said: Allah's Messenger, they at times narrate to us things which we find true. Thereupon Allah's Messenger (ﷺ) said: That is a word pertaining to truth which a jinn snatches away and then cackles into the ear of his friend as the hen does. And then they mix in it more than one hundred lies.
حَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا مَعْقِلٌ، - وَهْوَ ابْنُ عُبَيْدِ
 اللَّهِ - عَنِ الزُّهْرِيِّ، أَخْبَرَنِي يَحْيَى بْنُ عُرْوَةَ، أَنَّهُ سَمِعَ عُرْوَةَ، يَقُولُ قَالَتْ عَائِشَةُ سَأَلَ
 أُنَاسٌ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الْكُهَّانِ فَقَالَ لَهُمْ رَسُولُ اللَّهِ صلى الله عليه
 وسلم ‏"‏ لَيْسُوا بِشَىْءٍ ‏"‏ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ فَإِنَّهُمْ يُحَدِّثُونَ أَحْيَانًا الشَّىْءَ يَكُونُ حَقًّا
 ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ تِلْكَ الْكَلِمَةُ مِنَ الْجِنِّ يَخْطَفُهَا الْجِنِّيُّ فَيَقُرُّهَا فِي
 أُذُنِ وَلِيِّهِ قَرَّ الدَّجَاجَةِ فَيَخْلِطُونَ فِيهَا أَكْثَرَ مِنْ مِائَةِ كَذْبَةٍ ‏"‏ ‏.‏
