Al-Qasas - 28:85

إِنَّ الَّذِي فَرَضَ عَلَيْكَ الْقُرْآنَ لَرَادُّكَ إِلَى مَعَادٍ قُل رَّبِّي أَعْلَمُ مَن جَاء بِالْهُدَى وَمَنْ هُوَ فِي ضَلَالٍ مُّبِينٍ
[28:85]
Most surely He Who has made the Quran binding on you will bring you back to the destination. Say: My Lord knows best him who has brought the guidance and him who is in manifest error.
Verily He Who ordained the Qur'an for thee, will bring thee back to the Place of Return. Say: "My Lord knows best who it is that brings true guidance, and who is in manifest error."
Lo! He Who hath given thee the Qur'an for a law will surely bring thee home again. Say: My Lord is Best Aware of him who bringeth guidance and him who is in error manifest.
