In Naguib Mahfouz's work "Satan is Preaching," the arrival of a person brings a sense of anticipation among the elderly. This moment raises questions about the need for reflection or reassessment of their circumstances. The atmosphere is weighed down by unpleasant odors, symbolizing negativity that affects their environment.

The narrative suggests that these adverse effects penetrate deep, impacting even innocent creatures. The foreheads of animals may represent purity and innocence, contrasting with the corruption implied by the presence of this person. Mahfouz's writing delves into themes of hope, moral decay, and the need for critical self-evaluation in the face of challenging realities.
