Concerning Allah's statement,

وَلَا يَسْأَلُ حَمِيمٌ حَمِيمًا ﴿١٠﴾

يُبَصَّرُونَهُمْ ...

And no friend will ask a friend, though they shall be made to see one another.

Meaning, no close friend will ask his close friend about his condition while he sees him in the worst of conditions. He will be worried about himself and will not be able to think of others.

Al-`Awfi reported from Ibn `Abbas,

"Some of them will know others and they will be acquainted with each other. Then, they will flee from each other after that, as Allah says,

لِكُلِّ امْرِىءٍ مِّنْهُمْ يَوْمَئِذٍ شَأْنٌ يُغْنِيهِ

Every man that Day will have enough to make him careless of others.'' (80:37)

This honorable Ayah is similar to Allah's statement,

يأَيُّهَا النَّاسُ اتَّقُواْ رَبَّكُمْ وَاخْشَوْاْ يَوْماً لاَّ يَجْزِى وَالِدٌ عَن وَلَدِهِ وَلاَ مَوْلُودٌ هُوَ جَازٍ عَن وَالِدِهِ شَيْئاً إِنَّ وَعْدَ اللَّهِ حَقٌّ

O mankind!

Have Taqwa of your Lord, and fear a Day when no father can avail aught for his son, and nor a son avail aught for his father. Verily the promise of Allah is true. (31:33)

and He also says,

وَإِن تَدْعُ مُثْقَلَةٌ إِلَى حِمْلِهَا لاَ يُحْمَلْ مِنْهُ شَىْءٌ وَلَوْ كَانَ ذَا قُرْبَى

And if one heavily laden calls another to (bear) his load, nothing of it will be lifted even though he be near of kin. (35:18)

and He says,

فَإِذَا نُفِخَ فِى الصُّورِ فَلاَ أَنسَـبَ بَيْنَهُمْ يَوْمَئِذٍ وَلاَ يَتَسَآءَلُونَ

Then, when the Trumpet is blown, there will be no kinship among them that Day, nor will they ask of one another. (23:101)

and similarly He says,

يَوْمَ يَفِرُّ الْمَرْءُ مِنْ أَخِيهِ

وَأُمِّهِ وَأَبِيهِ

وَصَـحِبَتِهُ وَبَنِيهِ

لِكُلِّ امْرِىءٍ مِّنْهُمْ يَوْمَئِذٍ شَأْنٌ يُغْنِيهِ

That day shall a man flee from his brother, and from his mother and his father, and from his wife and his children.

Every man that Day will have enough to make him careless of others. (80:34-37)
