Some people asked the Prophet ﷺ regarding the soothsayers. He said, "They are nothing." They said, "O Messenger of Allah ﷺ! Some of their talks come true." The Prophet ﷺ said, "That word which happens to be true is what a Jinn snatches away by stealth (from the Heaven) and pours it in the ears of his friend (the foreteller) with a sound like the cackling of a hen. The soothsayers then mix with that word, one hundred lies."
عَائِشَةُ ؓ سَأَلَ أُنَاسٌ النَّبِيَّ ﷺ عَنِ الْكُهَّانِ فَقَالَ إِنَّهُمْ لَيْسُوا بِشَىْءٍ فَقَالُوا يَا رَسُولَ اللَّهِ فَإِنَّهُمْ يُحَدِّثُونَ بِالشَّىْءِ يَكُونُ حَقًّا قَالَ فَقَالَ النَّبِيُّ ﷺ تِلْكَ الْكَلِمَةُ مِنَ الْحَقِّ يَخْطَفُهَا الْجِنِّيُّ فَيُقَرْقِرُهَا فِي أُذُنِ وَلِيِّهِ كَقَرْقَرَةِ الدَّجَاجَةِ فَيَخْلِطُونَ فِيهِ أَكْثَرَ مِنْ مِائَةِ كَذْبَةٍ
