Allah will gather the first and the last…
Ibn Mas`ud said,
“On the Day of Resurrection, Allah will gather the first and the last, then a voice will call out, `Whoever is owed something by another, let him come forth and take it.’ And a man will rejoice if he is owed something or had been mistreated by his father or child or wife, even if it is little. ”
This is confirmed in the Book of Allah, where Allah 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.)
This was recorded by Ibn Abi Hatim.
