Al-Munafiqun - 63:6

سَوَاء عَلَيْهِمْ أَسْتَغْفَرْتَ لَهُمْ أَمْ لَمْ تَسْتَغْفِرْ لَهُمْ لَن يَغْفِرَ اللَّهُ لَهُمْ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الْفَاسِقِينَ
[63:6]
It is alike to them whether you beg forgiveness for them or do not beg forgiveness for them; Allah will never forgive them; surely Allah does not guide the transgressing people.
It is equal to them whether thou pray for their forgiveness or not. Allah will not forgive them. Truly Allah guides not rebellious transgressors.
Whether thou ask forgiveness for them or ask not forgiveness for them is all one for them; Allah will not forgive them. Lo! Allah guideth not the evil-living folk.
