وَسَوَآءٌ عَلَيۡهِمۡ ءَأَنذَرۡتَهُمۡ أَمۡ لَمۡ تُنذِرۡهُمۡ لَا يُؤۡمِنُونَ ١٠
And it is all the same for them whether you warn them or do not warn them - they will not believe.
Translation: Saheeh International (English)

Each word's meaning and sound
It is all the same to these disbelievers who oppose the truth, whether you, O Muhammad, warn them or you do not warn them. They will not accept what you have brought from Allah.
