Surah Al-Mu'minun, ayah 101

فَإِذَا نُفِخَ فِي ٱلصُّورِ فَلَآ أَنسَابَ بَيۡنَهُمۡ يَوۡمَئِذٖ وَلَا يَتَسَآءَلُونَ ١٠١

Fa idhā nufikha fis-sūri falā ansāba baynahum yawma'idhin walā yatasā'alūn

So when the Horn is blown, no relationship will there be among them that Day, nor will they ask about one another.
