And my advice will not benefit you - although I wished to advise you - If Allah should intend to put you in error. He is your Lord, and to Him you will be returned."
The Saheeh International Quran Translation
وَلَا يَنفَعُكُمْ نُصْحِىٓ إِنْ أَرَدتُّ أَنْ أَنصَحَ لَكُمْ إِن كَانَ ٱللَّهُ يُرِيدُ أَن يُغْوِيَكُمْ هُوَ رَبُّكُمْ وَإِلَيْهِ تُرْجَعُونَAnd my advice will not benefit you - although I wished to advise you - If Allah should intend to put you in error. He is your Lord, and to Him you will be returned."
