(Al-Qasas) 28 : 85
إِنَّ الَّذِي فَرَضَ عَلَيْكَ الْقُرْآنَ لَرَادُّكَ إِلَىٰ مَعَادٍ ۚ قُلْ رَبِّي أَعْلَمُ مَنْ جَاءَ بِالْهُدَىٰ وَمَنْ هُوَ فِي ضَلَالٍ مُبِينٍ
Indeed, the One Who imposed upon you this Reading will take you back to the place of return. You say: "My Lord is most knowing of who brings Guidance and who is in manifest astray".
Not the Arabic Quran, but Adhikr is the Guidance and Manifest Reading. Since the Lord is Impartial, one should confirm his destiny whether to Paradise or Hell by utilizing the Confirmed Truth Adhikr as told in verse 69: 51. See explanation 2: 38; 16: 125 and 25: 58-59.
