How many angels we have around us
Four angels accompany each person.
Two guardian angels, (one on the right and one on the left) write down the deeds of the person, the one on the right writing down the good deeds and the one on the left writing down the evil ones.
See soorah Qaaf (50) aayah 18.
There are two other angels, one in front of him and one behind each person, who protect him from attacks against him for as long as Allaah has written that he should remain (protected).
See Soorah ar Ra’d (13) aayah 11.
