According to Imam, in Islam, everything is a prelude to making true human beings. If this creature is left to itself, it will ruin and destroy the whole world.
Imam once said that the main topic of all discussions, the subject of all training and education and the goal of the knowledge of all of the Prophets has been human beings. They have all been appointed to train true human beings. They have all come to elevate this creature of nature from its natural level to super natural and up to the highest heaven. The ultimate goal of all the prophets' efforts is the human being.
Imam Khomeini explained that the Prophets have been appointed for the sake of humanity; for making true human beings. The books of the Prophets are to turn human beings into true human beings. The Holy Quran is the book of true human beings.
Imam stressed that the goal of all of the Prophets is human beings. Everything returns to them. They are the source of all deeds, good and righteous acts; at the same time, they can be the source of all satanic deeds and darkness.
