This book of light is life-giving, peace-giving as well as healing and guiding. Truly, man is always exposed to Satanic temptations. Hence, he should always be on guard against Satan. Satan’s enmity against human beings is not hidden to anyone. For further details and Satanic temptations, kindly refer to the book I have written under the title of “Satan and Passions”. Imam Sadiq (AS) has been reported by Abu Baseer as saying: “There are two ears for every heart.

Whenever a man intends to commit a sin, the spirit of faith says to him: ‘Do not do!, but Satan says to him: ‘Do it!’ When he is (sleeping) on her (adulteress) abdomen, the spirit of faith is taken away from him.”[^8] From this narration, it is inferred that a human being is always subject to Satanic temptations and he has to choose between truth and falsehood, between good and evil. The spirit of faith invites him to the path of truth and good, but Satan pushes him to falsehood and evil.

It is up to man to choose between these two. When the atmosphere of a house is warm and bright, it means there is light in the house, and when it is cold, it means that there is no sign of light in it. The same is true with the heart. When Satan tempts man to commit sin, the heart becomes dark, and when an angel persuades man to obey God’s command, the man’s heart becomes illuminated.

In this relation, the Messenger of Allah (SAW) has said: “There is no believer except that there two ears to his heart in his chest; one ear into which an angel blows and another ear into which the slinking Satan blows.

God helps the believer with the angel, for Allah the Glorified has said: “And He assisted them with a spirit from Him.”[^9] Imam Sadiq (AS) has said the same thing: “There is no believer except that in his heart there are two inward ears.”[^10] The Messenger of Allah (SAW) has been reported as saying: “In man there is a piece of flesh. If it is healthy, the other parts of the body are healthy too and when it gets sick, the other parts of the body get sick too.

That piece of flesh is the heart.”[^11] The Holy Prophet (SAW) has also said: “When the man’s heart is clean, his body shall be clean too, and whenever his heart is wicked, his whole body shall be wicked too.” ^12 The Holy Prophet (SAW) said: “The worst kind of blindness is the blindness of the heart.”[^13] An advice of Ameerul Mo’minin (AS) to his son is as follows: “O my son! One of the calamities is destitution. Worse than that is the disease of the heart.
