Surah Al-Ma'idah (The Table) is initiated with a command, as it clarifies what is permissible and what is forbidden after the command to fulfill the contracts. It includes a variety of legal and devotional rulings and clarifies the true faith, servitude, and divinity with reference to the directives of the believing nation with various other nations and denominations. It demonstrates the determination of these nations to worship Allah Almighty, to rule by what Allah Almighty has revealed of acts of worship and dealings to carry them out, and to act accordingly in a fair manner, without being influenced by personal feelings. In the current research, we also seek to explain the prohibition in this surah and analyze its structures, grammatical form and stylistic pattern in order to show the relationship between the structure in its linguistic form and grammatical relations with multiple functions in the blessed Quranic discourse and to understand the implications of the structures formed by the prohibition. This research adopted the method of prohibition as a constructive request that abounds in the legislative discourses characterized by enacting orders and prohibitions. This is what we found in this noble surah that the research deals with. The research also hypothesizes distinguishing the Quranic discourse for using this method with an obligatory authority that establishes its orders and prohibitions for special Quranic purposes, revealing its goals, analyzing its purposes, and investigating its legislative and doctrinal functions. This research consisted of two sections: the first one is related to Surah Al-Ma’idah and studying its Qur’anic purposes. The second one deals with the prohibition in this blessed surah in terms of studying its semantics and functions.
