33rd Ayah from Surah Al Mutaffifin
But they had not been sent as guardians over them.
though they were not sent to be their keepers-
But they (disbelievers, sinners) had not been sent as watchers over them (the believers).
while they were not sent as watchmen over them.
Yet they were not sent as guardians over them.
But they had not been sent as keepers over them!
