What will happen in that day? Allah says:
﴾وَأَن لَّيْسَ لِلإِنسَانِ إِلاَّ مَا سَعَى % وَأَنَّ سَعْيَهُ سَوْفَ يُرَى % ثُمَّ يُجْزَاهُ الْجَزَاء الأَوْفَى﴿
(And that man can have nothing but what he does (good or bad), % And that his deeds will be seen, % Then he will be recompensed with a full and the best recompense.) (An-Najm : 39-41)
On that day everyone will take his record, at that time he will remember all the good and evil deeds that he has done.
