Surat Al-'A`rāf - سورة الأعراف

فَرِيقًا هَدَىٰ وَفَرِيقًا حَقَّ عَلَيْهِمُ الضَّلَالَةُ ۗ إِنَّهُمُ اتَّخَذُوا الشَّيَاطِينَ أَوْلِيَاءَ مِن دُونِ اللَّهِ وَيَحْسَبُونَ أَنَّهُم مُّهْتَدُونَ

: A group He has guided, and a group deserved to be in error; (because) surely they took the Shayatin (devils) as Auliya' (protectors and helpers) instead of Allah, and consider that they are guided.
