From the point of view of Islam, the core of all values is faith in God. In the narrations, various topics about faith have been raised, some of which were mentioned under the title "Truth of Faith". Another topic that is discussed in the narrations about faith is "the perfection of faith". Of course, as it was mentioned, the Infalibles did not seek logical and classical discussions in the narrations, rather, they expressed something according to the situation of the audience and their needs. Therefore, the observed differences should not be the source of contempt and the illusion of difference between the narrations. These differences are, in fact, teachings that a teacher gives to his student or a coach to his coachee in order to remind him of some points to use in life. Some components of the perfection of faith are: avoiding violation of the right, correct understanding of religion, overcoming religion over lust and entrusting affairs to God. This article explains in detail the components of perfection faith and its description and interpretation.
