The semanticity of context is one of the most important signs of understanding of the Quranic text, and it is the result of studying the text, which is continuous and harmonious it expresses its meaning in relation of the former and the latter. Its goal is to take care of Allah Almighty’s Book in an exceptional manner to highlight the great efforts of commentators to extract wisdoms from the verses of Holy Book, and deduce the rulings from them. Thus, this article tackles and clarifies the understanding of a problem and an issue in the Qur’an’s issues which the Qur’anic sciences’ heritage manifested in the diversity of Qur’anic context in the Surat Al- Kahf (Cave) where we discussed the definition of diversity in Qur’anic context linguistically and terminologically. Then, the article talked about the context’s types, the methods and forms of diversity in the Qur'an through the study and application of diversity in the verses of the Surat Al- Kahf. In this article, the researcher found five positions for the contextual diversity in the Surat Al- Kahf in different names as we shall explain in this article. So, I liked to contribute to enrich the scientific library with the Qur’an and its sciences through the offering the article. In addition, I found the desire to present this topic as a participation to gain the honor to serve the Holy Qur’an. I seek Allah’s aid and guidance for surly He is bounteous and generous .
