Iblis, overhearing all this, became annoyed. He planned to tempt Job to corruption and disbelief, so he hastened to him. He tried to distract Job from his prayers by whispering to him about the good things in life, but Job was a true believer and would not let evil thoughts tempt him. This disturbed Iblis more; thus he began to hate Job even more.
