فَوَقَعَ الْحَقُّ وَبَطَلَ مَا كَانُوا يَعْمَلُونَ فَغُلِبُوا هُنَالِكَ وَانْقَلَبُوا صَاغِرِينَ وَأُلْقِيَ السَّحَرَةُ سَاجِدِينَ (الأعراف: 118-120)
فلمّا أَلْقَوْا قَالَ مُوسَى مَا جِئْتُمْ بِهِ السِّحْرُ إِنَّ اللَّهَ سَيُبْطِلُهُ إِنَّ اللَّهَ لَا يُصْلِحُ عَمَلَ الْمُفْسِدِينَ وَيُحِقُّ اللَّهُ الْحَقَّ بِكَلِمَاتِهِ وَلَوْ كَرِهَ الْمُجْرِمُونَ (يونس: 81-82)
إنَّمَا صَنَعُوا كَيْدُ سَاحِرٍ وَلَا يُفْلِحُ السَّاحِرُ حَيْثُ أَتَى (طه: 69)
