Angels

Ibn Katheer (may Allaah have mercy on him) said:

“The aayah (interpretation of the meaning): ‘For him (each person), there are angels in succession, before and behind him. They guard him by the Command of Allaah’ [al-Ra’d 13:10-11] means: each person has angels who take turns in guarding him by night and day, who protect him from evil and from accidents, just as other angels take turns in recording his deeds, good and bad, by night and by day.

Two angels, on the right and the left, record his deeds. The one on the right writes down his hasanaat (good deeds) and the one on his left writes down his sayi’aat (evil deeds).

Two other angels guard him and protect him, one from behind and one from in front.

So there are four angels by day and four others by night.”
