A study on the possibility of Satan’s impact on physical disease of human with emphasis on verse 41 of chapter Sad

The present article seeks to study the possibility of Satan’s impact on physical disease of human with emphasis on verse 41 of chapter Sad and the related narrations. The objective is to find answer to the question whether the devil had a role in various afflictions of Prophet Ayyub (AS), especially his physical illnesses and consequently other human beings, and if so, what is the mechanism? One of the findings of this study is that the devil can certainly affect human through temptations and motivating his/her emotions. When human acts according to satanic temptations, its definitive result will be his physical illnesses. Moreover, the concept and example of the Satan or demons in the language of verses and especially narrations go beyond the jinn devil and includes human demons and vermin that threaten human health such as all kinds of microbes.
