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.
