﴿ إِنَّا نَحْنُ نُحْىِ ٱلْمَوْتَىٰ وَنَكْتُبُ مَا قَدَّمُوا۟ وَءَاثَٰرَهُمْ ۚ وَكُلَّ شَىْءٍ أَحْصَيْنَٰهُ فِىٓ إِمَامٍۢ مُّبِينٍۢ ﴾

“Verily, We shall indeed bring the dead back to life; and We shall record whatever [deeds] they have sent ahead, and the traces [of good and evil] which they have left behind: for of all things do We take account in a record clear.”

Modern research has established that whatever a man utters remains preserved in the atmosphere in the form of vibrations or waves. Similarly, the image of the actions which a man performs remains preserved in the form of light waves. In other words, every individual in this world is being constantly video-recorded. It should be borne in mind that in this world, without a man’s knowledge and quite independent of his will, his utterances and actions, being completely recorded and preserved, could be replayed any time later.
