Abstrack   As has been explained in the Qur'an that there are several levels in the human soul which is better known as the level of anger and lust for lawamah and lust muthmainnah. Q.Susuf verse 53 has explained that there is a lust that always invites evil or evil deeds. Furthermore lust lawwamah has been explained in al-Qu'an surah al-Qiyamah verse 2. In the letter explains that he is a lust that resides in the human soul and it is he who always invites to maintain the wholeness as the most perfect human figure of God. The mutmainah lust has clearly been interpreted in QS al-Fajr verse 27, which most people interpret as lust that always invites goodness.
