9:113
مَا كَانَ لِلنَّبِىِّ وَٱلَّذِينَ ءَامَنُوٓا۟ أَن يَسْتَغْفِرُوا۟ لِلْمُشْرِكِينَ وَلَوْ كَانُوٓا۟ أُو۟لِى قُرْبَىٰ مِنۢ بَعْدِ مَا تَبَيَّنَ لَهُمْ أَنَّهُمْ أَصْحَـٰبُ ٱلْجَحِيمِ
9:113
After it has become clear that they are condemned to the Flaming Fire, it is not for the Prophet and those who believe to ask for the forgiveness of those who associate others with Allah in His Divinity even if they be near of kin. - Abul Ala Maududi (English)
