Surah At-Tawbah — Ayah 113 (9:113)
مَا كَانَ لِلنَّبِيِّ وَٱلَّذِينَ ءَامَنُوٓاْ أَن يَسۡتَغۡفِرُواْ لِلۡمُشۡرِكِينَ وَلَوۡ كَانُوٓاْ أُوْلِي قُرۡبَىٰ مِنۢ بَعۡدِ مَا تَبَيَّنَ لَهُمۡ أَنَّهُمۡ أَصۡحَٰبُ ٱلۡجَحِيمِ ١١٣
English translation (Saheeh International)
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.
Brief commentary
It is not right for the Prophet and the believers to seek forgiveness from Allah for the idolaters, even if they are their relatives, after it has become clear to them that they are the people of the fire of Hell – because they died as idolaters.
