Among the many works attributed to Amir Khosrow the famous Indian thinker and writer, there is a work that has serious differences with his other works and is brilliant as a jewel among other books. This book, entitled Dolarani and Khezer Khan , despite its great cultural and social importance, is an unknown work in Iran. Amir wrote this poem in Persian and while telling a lyrical story, he briefly narrated how Islam was spread and expanded by the kings of the Ghori dynasty in India. There are important sources from the arrival of Islam in Iran, but perhaps we have read and heard less about its arrival in other countries, especially those with strong indigenous and national civilizations. In this book, Amir, while narrating one of the Indian emotional stories, pays special attention to the changed social, political and even cultural conditions of that time in the subcontinent, especially intra-group and extra-group marriages (Muslim and non-Muslim). In other words, Amir from the window of this work, using the linguistic capacity and lexical range of Persian, Turkish and Hindu languages in which he is proficient, has expressed an important part of the social history and cultural changes of his time.
