And the record [of deeds] will be placed [open], and you will see the criminals fearful of that within it, and they will say, “Oh, woe to us! What is this book that leaves nothing small or great except that it has enumerated it?” And they will find what they did present [before them]. And your Lord does injustice to no one. (Quran 18:49)
