Quran 63:6 from Surah Al-Munaafiqoon on Divine Marvels.
سَوَآءٌ عَلَيۡهِمۡ أَسۡتَغۡفَرۡتَ لَهُمۡ أَمۡ لَمۡ تَسۡتَغۡفِرۡ لَهُمۡ لَن يَغۡفِرَ ٱللَّهُ لَهُمۡۚ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ
English translation: (It) is same for them whether you ask forgiveness for them or (do) not ask forgiveness for them Never will forgive Allah [to] them Indeed Allah (does) not guide the people the defiantly disobedient
Transliteration: sawaon alayhim astaghfarta lahum am lam tastaghfir lahum lan yaghfira al-lahu lahum inna al-laha la yahdi al-qawma al-fasiqina
