Verse 85

إِنَّ ٱلَّذِى فَرَضَ عَلَيْكَ ٱلْقُرْءَانَ لَرَآدُّكَ إِلَىٰ مَعَادٍ قُل رَّبِّىٓ أَعْلَمُ مَن جَآءَ بِٱلْهُدَىٰ وَمَنْ هُوَ فِى ضَلَـٰلٍ مُّبِينٍ

Indeed the One who decreed the Quran for you will surely take you to the Hereafter. Say; my Lord knows best who is guided, and who is in manifest straying.
