The traditions of  Tinat and free will of human being

According to Some traditions in Shia’s hadith collections, the origin of human being or the very clay from which human being is created, and it is called‘Tinat’ in Shia texts, has a great role in man’s happiness or misery or becoming a man a believer or nonbeliever. According to the traditions God has created the believers from a pleasant and good quality clay which is called ‘Tinat Elleen’ while He has created the nonbelievers from an unpleasant clay which is called ‘Tinat Sejjin’. At first sight these traditions are totally contrary to the beliefs of free will of human being and the justice of God. Therefore different types of solutions has been suggested by the Islamic scholars to eliminate this contradiction. At this essay those solutions are reported, studied and criticized, and at the end a new attitude and solution has been suggested to interpret and explicate this traditions.
