Surah Al-Qasas (The Stories), Verse 85

اِنَّ الَّذِیْ فَرَضَ عَلَیْكَ الْقُرْاٰنَ لَرَآدُّكَ اِلٰی مَعَادٍ قُلْ رَّبِّیْۤ اَعْلَمُ مَنْ جَآءَ بِالْهُدٰی وَمَنْ هُوَ فِیْ ضَلٰلٍ مُّبِیْنٍ ۟

Innal lazee farada 'alaikal Qur-aana laraaadduka ilaa ma'aad; qur Rabbeee a'lamu man jaaa'a bil hudaa wa man huwa fee dalaalim mubeen

“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."”
