In the Glorious Qur'an (Q.39:28), it is stated that the uniqueness of the Qur'an lies in the fact that it is revealed in Arabic. The verse says, "An Arabic Qur'an, without any crookedness (therein), that they may avoid (any harm)." This means that the Qur'an was revealed in the Arabic language, which was the language of the people to whom it was revealed. The Arabic language is considered by Muslims to be a unique and beautiful language that is well-suited for the expression of complex ideas and concepts. The Qur'an's use of Arabic language is seen as a sign of its divine origin and a testament to its power and beauty. The other options, such as being highly educative, in brief form, or revealed piecemeal, are not mentioned as the uniqueness of the Qur'an in this verse.
