The issue of love in the religious and mystical literature

. In the definition of love, there is a controversy between scholars and the ethics of the scholars, and this difference is so great that some of its true definition is considered impossible and believes that love is the language of the present, not the carpet. Muslim mystics, inspired by Qur'anic and narrative teachings, discuss the issue of love in their works, and in what aspects, dimensions and works have been spoken. Universe like Feyz Kashani, as interpreter, scholar and thinker of the ethics of theology, firstly, by following the verbal and practical aspects of the infallibles, and secondly, influencing the thoughts of some mystics and philosophers such as Ghazali, Ibn Arabi and Mulla Sadra, into the theme of affection in his works. Meanwhile, one of the important pitfalls of the discussion of affection, among such scholars, including Faiz Kashani, is its relationship with knowledge. This important aspect in the viewpoint of the mystics played a pivotal role, and the followers of this category have taken into consideration the narrative teachings. Faiz Kashani, also inspired by hadiths, such as the Hadiths of the hidden secret and Hadith "Ghorbnavafel", and the influence of the thoughts of the mystics, have shown this relationship in the clarification of the theme of affection. This paper, by descriptive and analytical method, examines and analyzes the mystical approaches of love in the light of grace.
