Imam Sadiq (a.s) said: “If you realize that a scientist loves this world, accuse him regarding your religion since whoever loves something is its slave. God revealed the following to Prophet David: “Do not let a scientist who is attracted to the world act as a middle man between you and I, since he will prevent you from loving Me. Such people are the robbers of those who seek Me, and the least that I shall do is to deprive them of the sweetness of My supplication.”
