إِنَّ ٱلَّذِى فَرَضَ عَلَيْكَ ٱلْقُرْءَانَ لَرَآدُّكَ إِلَىٰ مَعَادٍ ۚ قُل رَّبِّىٓ أَعْلَمُ مَن جَآءَ بِٱلْهُدَىٰ وَمَنْ هُوَ فِى ضَلَـٰلٍ مُّبِينٍ ۝٨٥

28:85 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.
