[2:212] Decked out fair to the disbelievers is the life of this world; and they deride the believers; but those who fear shall be above them on the Day of Resurrection; and God sustains whomever He will without reckoning.
Unknowingly, they were deceived. The increasing darkness of their vision caused them to slander and deride His friends (s). When the error of ignorance is dispelled from their hearts at a moment in which they will experience despair, they will come to know the one who is in a state of loss among those who have gone far astray.
