Imam Khomeini guided believers how to get rid of moral decline

Imam in his famous work of "an exposition on Forty Hadith" has undertaken a variety of discussions 

According to Imam, among other vices present in the person who is afflicted with ‘ujb is that of viewing others with contempt.

He considers their deeds as insignificant, however superior they may be to his own. This is also one of the ways of human destruction, and a peril on the path of true humanness.  

Another ill effect of this vice is that it manifests itself in the form of another fatal disease that is, the sin of pride (of which we shall have to say more later) and other vices, which are direct or indirect products of it.

 A full treatment of all of them would make our discussion lengthy it is enough to mention it that a person afflicted with ‘ujb should know that this vice sows the seeds of many other vices and serves as the source of such offences, each one of which is enough for earning everlasting damnation by itself. If one tries to properly understand these vices, and studies the traditions and teachings handed down by the Prophet (S), or the Imams of his household (peace be upon them), he will realize the necessity of rectifying his self, and will seek to get rid of this vice before, God forbid, he carries it with him to the next world.

If this happens, once his eyes are closed on this world and opened to world of barzakh and, thereafter, to the Day of Resurrection, he will see that the persons who committed major sins are better off than him.  

God Almighty will show him that he not only did not perform any worship for His sake, but also that his works of devotion and piety only took him away from God and have removed him away from his goal, Imam further explains. 

Not only his faith and deeds have been invalid, but they have also served as the cause of eternal damnation and painful chastisement in hell. God forbid, lest God Almighty judges anybody with the criteria of His justice, because, as mentioned previously, not a single individual, from the first to the last, will find any way of redemption.

The prayers and supplications of His chosen servants and the infallible Imams (peace be upon them) are replete with the confessions of their failure to do justice to the demands of the worship and the service of Lord. While the most perfect of all creatures and the man nearest to God (i.e. the Prophet [peace be upon him]) utters:

"We did not know You as You deserve to be known. We did not worship You as You deserve to be worshipped."
