Therefore purifying and disciplining of the selves can be considered as an important aim of the prophets; just as Almighty Allah says: لَقَدْ مَنَّ اللَّهُ عَلَى الْمُؤمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولاً مِّنْ أَنْفُسِهِمْ يَتْلُواْ عَلَيْهِمْ ءَايَتِهِ وَيُزَكِّيْهِمْ وَيُعَلِّمُهُمُ الْكِتَبَ وَالْحِكْمَةَ وَإِنْ كَانُواْ مِنْ قَبْلُ لَفِى ضَلَلٍ مُّبِينٍ‏ “Certainly Allah conferred a benefit upon the believers when He raised among them an Apostle from among themselves, reciting to them His communications and purifying them, and teaching them the Book and the wisdom, although before that they were surely in manifest error.” (3:164) The Holy Prophet (S) said: “I advise you to follow good manners and ethics as Almighty Allah has raised me for the same purpose.”[^2] Imam Ali (a.s.) has narrated from the Messenger of Allah (S) that he said: “I have been sent for the perfection of morals and improving the manners (of people).”[^3] Motivating people to the worship of one God and submission to His commands.

So much so that it is mentioned that the aim of creation of man is not but the worship of God as mentioned in the following verse: وَلَقَدْ بَعَثْنَا فِى كُلِّ أُمَّةٍ رَّسُولاً أَنِ اعْبُدُواْ اللَّهَ وَاجْتَنِبُواْ الطَّغُوتَ “And certainly We raised in every nation an apostle saying: Serve Allah and shun the Shaitan.” (16:36) وَمَا خَلَقْتُ الْجِنَّ وَالْإِنسَ إِلَّا لِيَعْبُدُونِ “And I have not created the jinn and the men except that they should serve Me.” (51:56) By showing such a program to the people, the prophets called them to get assured success in the hereafter.
