Sura al-Anʿām 6:110

وَنُقَلِّبُ أَفْـِٔدَتَهُمْ وَأَبْصَٰرَهُمْ كَمَا لَمْ يُؤْمِنُوا۟ بِهِۦٓ أَوَّلَ مَرَّةٍ وَنَذَرُهُمْ فِى طُغْيَٰنِهِمْ يَعْمَهُونَ

wa-nuqallibu afʾidatahum wa-abṣārahum ka-mā lam yuʾminū bihi awwala marratin wa-nadharuhum fī ṭughyānihim yaʿmahūna

We (too) shall turn to (confusion) their hearts and their eyes, even as they refused to believe in this in the first instance: We shall leave them in their trespasses, to wander in distraction.

Sura al-Kahf 18:18

وَتَحْسَبُهُمْ أَيْقَاظًا وَهُمْ رُقُودٌ وَنُقَلِّبُهُمْ ذَاتَ ٱلْيَمِينِ وَذَاتَ ٱلشِّمَالِ وَكَلْبُهُم بَٰسِطٌ ذِرَاعَيْهِ بِٱلْوَصِيدِ لَوِ ٱطَّلَعْتَ عَلَيْهِمْ لَوَلَّيْتَ مِنْهُمْ فِرَارًا وَلَمُلِئْتَ مِنْهُمْ رُعْبًا

wa-taḥsabuhum ayqāẓan wa-hum ruqūdun wa-nuqallibuhum dhāta l-yamīni wa-dhāta l-shimāli wa-kalbuhum bāsiṭun dhirāʿayhi bil-waṣīdi lawi iṭṭalaʿta ʿalayhim la-wallayta minhum firāran wa-la-muliʾta minhum ruʿban

Thou wouldst have deemed them awake, whilst they were asleep, and We turned them on their right and on their left sides: their dog stretching forth his two fore-legs on the threshold: if thou hadst come up on to them, thou wouldst have certainly turned back from them in flight, and wouldst certainly have been filled with terror of them.
