وَلَا يَنفَعُكُمْ نُصْحِىٓ إِنْ أَرَدتُّ أَنْ أَنصَحَ لَكُمْ إِن كَانَ ٱللَّهُ يُرِيدُ أَن يُغْوِيَكُمْ ۚ هُوَ رَبُّكُمْ وَإِلَيْهِ تُرْجَعُونَ
My counsel will not profit you if I were minded to advise you, if Allah's will is to keep you astray. He is your Lord and unto Him ye will be brought back.
