Quran 2:6 from Surah Al-Baqara on Divine Marvels.
إِنَّ ٱلَّذِينَ كَفَرُواْ سَوَآءٌ عَلَيۡهِمۡ ءَأَنذَرۡتَهُمۡ أَمۡ لَمۡ تُنذِرۡهُمۡ لَا يُؤۡمِنُونَ
English translation: Indeed those who disbelieve[d] (it) is same to them whether you warn them or not you warn them not they believe
Transliteration: inna alladhina kafaru sawaon alayhim a-andhartahum am lam tundhir'hum la yu'minuna
