The Role of Comparative Literature in Expressing the Similarities between Different Islamic Customs

By highlighting and expressing the importance of comparative literature in monotheism, the present article depicts Islamic customs and their closeness to each other in all parts of the world. First of all, comparative literature acknowledges the universality of Islamic customs from the earliest days, and in this regard, the influence of Arabic customs on some other customs is also a good proof of this claim. The purpose of this article is to express the differences, similarities and the role of comparative literature in the monotheism in Islamic customs as well as depicting the literary possessions of different nations and the role of comparative literature in monotheism. This article deals with the issue of the origin and interaction between Arabic, Pashto and Dari Persian customs in the storytelling of the literates of the said literature in a comprehensive way. The story of Layla and Majnun has been selected as a literary example in the mentioned customs. Story literature is not specific to one nation or group, but it includes the mental and intellectual exudations of human beings all over the world. Findings show that the versions of Layla and Majnun story have many similarities in terms of the story and also in terms of the protagonist of the story in Arabic (Qays is Majnun's counterpart in Arabic), Pashto and Persian literature, but they also have differences.
