The Prophet said that there are angels with every man and woman. The Quran says: إِذْ يَتَلَقَّى الْمُتَلَقِّيَانِ عَنِ الْيَمِينِ وَعَنِ الشِّمَالِ قَعِيدٌ  (50:17) There is an angel to our right and an angel to our left. Each angel makes records and notes. Another verse says that our actions are being recorded: مَا يَلْفِظُ مِنْ قَوْلٍ إِلَّا لَدَيْهِ رَقِيبٌ عَتِيدٌ (50:18) Not only our words, but even our video recording is going on. Both our speech and actions are being recorded I understood this through a real story. There was a story from Delhi published in newspapers. When in Delhi the system of video recording was installed on roads for controlling traffic, a policeman held the owner of a three-wheeler. He parked his three-wheeler at a no-parking spot. He took out a cigarette and began smoking. The policeman told him that he had parker at a no-parking spot. The person began to argue with the policeman. He denied the charge. The policeman took him to his office.

There was a control room in the office, which had an officer. The policeman told the officer that this person had parked his vehicle at no-parking. When the officer asked him, he completely denied. He lied that he never parked his vehicle there. The recording done on TV was replayed. When it was replayed, the person saw everything on screen. He saw that he was riding his three-wheeler, then stopped at a no-parking spot where he met a friend, he took out two cigarettes and both began to smoke. There he was busy chatting. The policeman stopped him and he refused to accept his fault. He saw everything in the record. He was speechless. He was left speechless.

This is what the Quran also says. The Prophet also told people about this. This is what he meant by saying: I am an open warner. أَنَا النَّذِيرُ العُرْيَانُ (Sahih al-Bukhari 6482) The Prophet told people in advance about what was going to happen: God's angel is doing your video recording. Every single aspect about you is being recorded. You will be presented before God after death. You won't be able to deny anything there. You need to prepare today itself, so that you can be safe from God's punishment.
