فَإِذَا نُفِخَ فِي ٱلصُّورِ فَلَآ أَنسَابَ بَيۡنَهُمۡ يَوۡمَئِذٖ وَلَا يَتَسَآءَلُونَ ١٠١
So when the Horn is blown, no relationship will there be among them that Day, nor will they ask about one another.
Translation: Saheeh International (English)
Each word's meaning and sound
Then when the angel appointed to blow the Trumpet will blow the second time which will announce the Day of Judgment, there will be no relations between them to boast through, due to their being engrossed in the horrors of the Hearafter, and they will not question one another due to their being engrossed in what concerns them.
