According to public relations and international affairs of the scientific and cultural institution of DarolErfan, Professor Hussein Ansarian pointed out in his lecture in the Husseinieh Hazrat Qasim (as): The Shiite scholars have written a great deal of different books on various sciences. A series of their works, which are the best works throughout human history, are their moral books. Of course, these books are derived from the Holy Quran and the narrations of Ahlulbayt (peace be upon them).
The Scholar, exegete and the researcher of the holy Quran mentioned: based on the verses of the Holy Quran and the narrations from the Infallible Imams (peace be upon them), morality is divided into two parts: positive and negative morality, divine and evil one and the good deeds and bad ones. If someone is suffering from lack of morality, this shortage of morality is a veil between him and Allah's mercy. The moral vices is making human beings far from the Mercy of Allah Almighty.
