﴿ سَوَآءٌ عَلَيْهِمْ أَسْتَغْفَرْتَ لَهُمْ أَمْ لَمْ تَسْتَغْفِرْ لَهُمْ لَن يَغْفِرَ ٱللَّهُ لَهُمْ ۚ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلْفَٰسِقِينَ ﴾

“As for them it is all the same whether thou dost pray that they be forgiven or dost not pray for them: God will nor forgive them - for, behold, God does not bestow His guidance upon such iniquitous folk.”
