Surah Yunus, ayah 32

فَذَٰلِكُمُ ٱللَّهُ رَبُّكُمُ ٱلۡحَقُّۖ فَمَاذَا بَعۡدَ ٱلۡحَقِّ إِلَّا ٱلضَّلَٰلُۖ فَأَنَّىٰ تُصۡرَفُونَ ٣٢

Fadhālikumullāhu rabbukumul-haqqu famādhā ba'dal-haqqi illad-dalālu fa annā tusrafūn

For that is Allāh, your Lord, the Truth. And what can be beyond truth except error? So how are you averted?
