Surah At-Tawbah — Ayah 80 (9:80)
ٱسۡتَغۡفِرۡ لَهُمۡ أَوۡ لَا تَسۡتَغۡفِرۡ لَهُمۡ إِن تَسۡتَغۡفِرۡ لَهُمۡ سَبۡعِينَ مَرَّةٗ فَلَن يَغۡفِرَ ٱللَّهُ لَهُمۡۚ ذَٰلِكَ بِأَنَّهُمۡ كَفَرُواْ بِٱللَّهِ وَرَسُولِهِۦۗ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ ٨٠
English translation (Saheeh International)
Ask forgiveness for them, [O Muḥammad], or do not ask forgiveness for them. If you should ask forgiveness for them seventy times - never will Allāh forgive them. That is because they disbelieved in Allāh and His Messenger, and Allāh does not guide the defiantly disobedient people.
Brief commentary
Allah will never forgive the hypocrites, even if the Messenger was to ask for their forgiveness, because they do not deserve to be forgiven, nno matter how much forgiveness is sought for them. They disbelieved in Allah and His Messenger and they deliberately oppose Allah’s sacred law.
