Al-Baqarah 2:6
إِنَّ ٱلَّذِينَ كَفَرُوا۟ سَوَآءٌ عَلَيْهِمْ ءَأَنذَرْتَهُمْ أَمْ لَمْ تُنذِرْهُمْ لَا يُؤْمِنُونَ
Inna allatheena kafaroo sawaonAAalayhim aanthartahum am lam tunthirhum layu/minoon
Indeed, those who disbelieve - it is all the same for them whether you warn them or do not warn them - they will not believe.
Surely for those who have disbelieved, it is all the same whether you warn them or you warn them not: they do not believe.
