The duty of messengers to convey the message

وَلَا يَنفَعُكُمْ نُصْحِىٓ إِنْ أَرَدتُّ أَنْ أَنصَحَ لَكُمْ إِن كَانَ ٱللَّهُ يُرِيدُ أَن يُغْوِيَكُمْ ۚ هُوَ رَبُّكُمْ وَإِلَيْهِ تُرْجَعُونَ

And my advice will not benefit you - although I wished to advise you - if Allāh should intend to put you in error. He is your Lord, and to Him you will be returned."
