ما كانَ لِلنَّبِيِّ وَالَّذينَ آمَنوا أَن يَستَغفِروا لِلمُشرِكينَ وَلَو كانوا أُولي قُربىٰ مِن بَعدِ ما تَبَيَّنَ لَهُم أَنَّهُم أَصحابُ الجَحيمِ
It’s not for the Prophet and the believers to seek forgiveness for the polytheists, even if they were their relatives, after it became clear to them that they are inhabitants of the blazing Fire.
