Flies : A weak, stubborn, dirty man, and eating it is a dirty livelihood or forbidden money . Many flies are a harmful enemy, but if the traveler sees the flies falling on his head, he is afraid that he will cross the road and go with his money, because God Almighty says : “ And if the flies rob them of something, they will not save it from it .” Likewise, if the flies fall on something from him, meaning from his money, thieves fear him . And it was said who killed a fly, got a rest and health of the body .
