Satan cannot be successful in his attempts to seduce a devout practicing believer by coming upon him from behind or before him or from his left. Instead he tries to approach him from his right and tempt him to display and ostentation and into pride in his virtue and his good deeds. He whispers to him how good a believer he is and gradually throws him to perdition through self-conceit and the desire to be praised by others for his good deeds. For example if a believer does the supererogatory late night prayer and then proclaims it everywhere with the desire to be praised by others and if he attributes to himself his accomplishments and good deeds and criticizes others behind their back it means that he has fallen under the influence of Satan. This is perilous for a believer so a believer must be incessantly alert to Satan's coming upon him from his right.
