The Keeper Angels and the Angel Scribes(Recorders):

وَإِنَّ عَلَيْكُمْ لَحَافِظِينَ كِرَامًا كَاتِبِينَ يَعْلَمُونَ مَا تَفْعَلُونَ  [1]

“And most surely there are keepers over you, Honorable recorders; they (the angels) know what you do.”

No doubt, the Almighty God Knows more than anybody else what we humans are doing. But for further emphasis and for man to feel more responsible, God has stationed may Keepers for him: One of them is the group of angels.

مَا يَلْفِظُ مِنْ قَوْلٍ إِلَّا لَدَيْهِ رَقِيبٌ عَتِيدٌ  [2]

 “He utters not a word but there is by him a watcher at hand.”

إِذْ يَتَلَقَّى الْمُتَلَقِّيَانِ عَنْ الْيَمِينِ وَعَنْ الشِّمَالِ قَعِيدٌ  [3]

“When the two receivers receive, sitting on the right and on the left. (Remember there are two angels who record what you are doing).”

Imam Musa Ibn Ja’afar(a.s) was asked: will the recorder angels become aware of the intentions of the person who wants to perform sins or good things? Imam (a.s) asked: Is the smell of sewage and a fragrance the same? The narrator replied: No! Imam (a.s) replied: When a person intends to carry out a good deed, his breath becomes good – smelling. The right-hand angel will tell the left-hand angel: be alert, the person wants to do the right thing. And when the man carried out the intended right thing, the man’s tongue will turn into a pen for the recorder – angel and his saliva will become her ink.

But when a man intends to do something evil, his breath will become foul - smelling. The angel on the left side will then make the other angel alert, telling her: Take care, he intends to do something wrong. His tongue and saliva then will be used as a pen and ink to write a report on the sinner.[4]
