إِنَّ ٱلَّذِي فَرَضَ عَلَيۡكَ ٱلۡقُرۡءَانَ لَرَآدُّكَ إِلَىٰ مَعَادٖۚ قُل رَّبِّيٓ أَعۡلَمُ مَن جَآءَ بِٱلۡهُدَىٰ وَمَنۡ هُوَ فِي ضَلَٰلٖ مُّبِينٖ
English translation: Indeed He Who ordained upon you the Quran (will) surely take you back to a place of return Say My Lord (is) most knowing (of him) who comes with the guidance and who he (is) in an error manifest
Transliteration: inna alladhi farada alayka al-qur'ana laradduka ila ma'adin qul rabbi a'lamu man jaa bil-huda waman huwa fi dalalin mubinin
