Surah At-Taubah Verse 113 - English Translation by Muhammad Mahmoud Ghali
Surah At-Taubahمَا كَانَ لِلنَّبِيِّ وَٱلَّذِينَ ءَامَنُوٓاْ أَن يَسۡتَغۡفِرُواْ لِلۡمُشۡرِكِينَ وَلَوۡ كَانُوٓاْ أُوْلِي قُرۡبَىٰ مِنۢ بَعۡدِ مَا تَبَيَّنَ لَهُمۡ أَنَّهُمۡ أَصۡحَٰبُ ٱلۡجَحِيمِ
In no way should the Prophet and the ones who have believed ask forgiveness for the associators, (Those who associate others with ' Allah) even if they are near of kin, even after it has become evident to them that they will be the companions (i.e., inhabitants) in Hell-Fire
