each person has guardian angels before him and behind, watching over him by God’s command. God does not change the condition of a people [for the worse] unless they change what is in themselves, but if He wills harm on a people, no one can ward it off–– apart from Him, they have no protector.
For each person there are successive angels, before him and behind him, guarding him by the command of God. Indeed, God does not change the condition of a people until they change what is within themselves. And when God wills harm for a people, there is no turning it back, and they have no protector besides him.
Mu'aqqibat names those who follow one after another in succession, and the phrase min amri-llah has been read two ways: as guarding by God's command, and as guarding from what he has decreed. The famous middle clause takes a people as its subject, which puts its natural scale at a community's shared condition rather than one private life. The change it describes runs in both directions, as the rest of the verse makes clear.
