Sahih Muslim , Book 26, Hadith 5535 (USC-MSA) ⓘ
'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.
وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ يَحْيَى، بْنِ عُرْوَةَ بْنِ الزُّبَيْرِ عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ الْكُهَّانَ كَانُوا يُحَدِّثُونَنَا بِالشَّىْءِ فَنَجِدُهُ حَقًّا قَالَ " تِلْكَ الْكَلِمَةُ الْحَقُّ يَخْطَفُهَا الْجِنِّيُّ فَيَقْذِفُهَا فِي أُذُنِ وَلِيِّهِ وَيَزِيدُ فِيهَا مِائَةَ كَذْبَةٍ " .
