وَوُضِعَ ٱلْكِتَٰبُ فَتَرَى ٱلْمُجْرِمِينَ مُشْفِقِينَ مِمَّا فِيهِ وَيَقُولُونَ يَٰوَيْلَتَنَا مَالِ هَٰذَا ٱلْكِتَٰبِ لَا يُغَادِرُ صَغِيرَةًۭ وَلَا كَبِيرَةً إِلَّآ أَحْصَىٰهَا ۚ وَوَجَدُوا۟ مَا عَمِلُوا۟ حَاضِرًۭا ۗ وَلَا يَظْلِمُ رَبُّكَ أَحَدًۭا
And the Book is placed, and thou seest the guilty fearful of that which is therein, and they say: What kind of a Book is this that leaveth not a small thing nor a great thing but hath counted it! And they find all that they did confronting them, and thy Lord wrongeth no-one.
Surah Al-Kahf(18:49)
