Surah Al-Munafiqun — Ayah 6 (63:6)
سَوَآءٌ عَلَيۡهِمۡ أَسۡتَغۡفَرۡتَ لَهُمۡ أَمۡ لَمۡ تَسۡتَغۡفِرۡ لَهُمۡ لَن يَغۡفِرَ ٱللَّهُ لَهُمۡۚ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ ٦
English translation (Saheeh International)
It is all the same for them whether you ask forgiveness for them or do not ask forgiveness for them; never will Allāh forgive them. Indeed, Allāh does not guide the defiantly disobedient people.
Brief commentary
It is the same whether you, O Messenger, seek forgiveness for their sins or you do not seek forgiveness for them. Allah will never forgive their sins. Allah does not guide those who go against His obedience and who persist in disobeying Him.
