Surah Al-A'raf 7:30

فَرِيقًا هَدَىٰ وَفَرِيقًا حَقَّ عَلَيْهِمُ ٱلضَّلَـٰلَةُ ۗ إِنَّهُمُ ٱتَّخَذُوا۟ ٱلشَّيَـٰطِينَ أَوْلِيَآءَ مِن دُونِ ٱللَّهِ وَيَحْسَبُونَ أَنَّهُم مُّهْتَدُونَ

A group [of you] He guided, and a group deserved [to be in] error. Indeed, they [i.e., the latter] had taken the devils as allies instead of Allāh while they thought that they were guided.

Translation: Saheeh International

Tafsir

A party of you He has guided while another party has deserved to go astray — they have taken devils as patrons instead of God that is other than Him and think that they are guided’.
