التوبة — At-Taubah Ayat 113
مَا كَانَ لِلنَّبِيِّ وَالَّذِيْنَ اٰمَنُوْٓا اَنْ يَّسْتَغْفِرُوْا لِلْمُشْرِكِيْنَ وَلَوْ كَانُوْٓا اُولِيْ قُرْبٰى مِنْۢ بَعْدِ مَا تَبَيَّنَ لَهُمْ اَنَّهُمْ اَصْحٰبُ الْجَحِيْمِ
Mā kāna lin-nabiyyi wal-lażīna āmanū ay yastagfirū lil-musyrikīna wa lau kānū ulī qurbā mim ba‘di mā tabayyana lahum annahum aṣḥābul-jaḥīm(i).
"It is not for the Prophet and those who have believed to ask forgiveness for the polytheists, even if they were relatives, after it has become clear to them that they are companions of Hellfire."
