مَا كَانَ لِلنَّبِيِّ وَٱلَّذِينَ ءَامَنُوٓاْ أَن يَسۡتَغۡفِرُواْ لِلۡمُشۡرِكِينَ وَلَوۡ كَانُوٓاْ أُوْلِي قُرۡبَىٰ مِنۢ بَعۡدِ مَا تَبَيَّنَ لَهُمۡ أَنَّهُمۡ أَصۡحَٰبُ ٱلۡجَحِيمِ

Maa kaana lin nabiyyi wallazeena aamanooo 'any yastaghfiroo lil mushrikeena wa law kaanoo ulee qurbaa min ba'di maa tabiyana lahum annahum Ashaabul jaheem

It is not fitting, for the Prophet and those who believe, that they should pray for forgiveness for Pagans, even though they be of kin, after it is clear to them that they are companions of the Fire.
