2:6
إِنَّ ٱلَّذِينَ كَفَرُوا۟ سَوَآءٌ عَلَيْهِمْ ءَأَنذَرْتَهُمْ أَمْ لَمْ تُنذِرْهُمْ لَا يُؤْمِنُونَ
inna alladhīna kafarū sawāon ʿalayhim a-andhartahum am lam tundhir'hum lā yu'minūna
Indeed, those who disbelieve - it is all the same for them whether you warn them or do not warn them - they will not believe.

As for those who disbelieve, it makes no difference whether you warn them or not: they will not believe.
— M. A. S. Abdel Haleem
Verily, those who disbelieve, it is the same to them whether you (O Muhammad صلى الله عليه وسلم) warn them or do not warn them, they will not believe.
— Muhammad Muhsin Khan & Muhammad Taqi-ud-Din al-Hilali
