Over every soul there is a keeper (if read la-mā, then mā is extra, and in, is softened in place of the hardened form with its subject omitted, that is to say, innahu; the lām is [a particle] for separation; if read lammā, then in is for negation and lammā means illā, 'except that') - the watcher is an angel that keeps a record of its deeds, both the good and the evil.
