فَإِذَا نُفِخَ فِي الصُّورِ فَلَا أَنسَابَ بَيْنَهُمْ يَوْمَئِذٍ وَلَا يَتَسَاءَلُونَ (101)
(23:101) Then, when the Trumpet will be blown, all (worldly) relations between them shall cease to function and they will not inquire about one another *94 .
*94) It dces not mean that the father will not remain "father" and the son will not remain "son", etc.. It only means that they will not be able to help each other, nor shall they be able to enquire about each other as father and son, for each one will be worried and anxious about his own plight.
