فَرِيقًا هَدَىٰ وَفَرِيقًا حَقَّ عَلَيْهِمُ ٱلضَّلَٰلَةُ ۗ إِنَّهُمُ ٱتَّخَذُوا۟ ٱلشَّيَٰطِينَ أَوْلِيَآءَ مِن دُونِ ٱللَّهِ وَيَحْسَبُونَ أَنَّهُم مُّهْتَدُونَ
A party hath He led aright, while error hath just hold over (another) party, for lo! they choose the devils for protecting supporters instead of Allah and deem that they are rightly guided.
Surah Al-A'raaf(7:30)
