Taberî prefers not to confine the attribute of 'mübin' (manifest/clear) to a specific part of the Book (such as lawful-unlawful, guidance-misguidance, or certain letters omitted from Arabic), but rather embraces that it encompasses all the meanings contained in the book (lawful, unlawful, prohibition, and all other varieties of meaning). He argues that the expression 'al-Kitab al-Mübin' in this verse means that it is clear and comprehensible in all its content to whoever reads it and reflects upon what it contains.

والصواب من القول في ذلك عندي أن يقال: معناه: هذه آيات الكتاب المبين، لمن تلاه وتدبر ما فيه من حلاله وحرامه ونهيه وسائر ما حواه من صنوف معانيه؛ لأن الله جل ثناؤه أخبر أنه مبين، ولم يخص إبانته عن بعض ما فيه دون جميعه، فذلك على جميعه

According to Zemahşerî, the expression 'al-Kitab al-Mübin' can be understood in several ways: it being miraculous verses that render the Arabs incapable and silent, its clarity that shows to those who reflect upon it that it comes from Allah, the fact that its meaning does not remain hidden to the Arabs due to it being revealed in the Arabic language, or that it has clarified the story of Yusuf which the Jews had asked about. As a basis for this last interpretation, it is narrated that Jewish scholars suggested to the polytheist elders to ask the Prophet why the family of Jacob migrated from the Levant to Egypt and about the story of Yusuf.

فقد روي أن علماء اليهود قالوا لكبراء المشركين : سلوا محمدا لم انتقل آل يعقوب من الشام إلى مصر ؟ وعن قصة يوسف

According to this exegete, 'al-Kitab al-Mübin' may be the Preserved Tablet or the book that Allah promised to reveal to Muhammad; the attribute 'mübin' can be explained in multiple ways such as the clarification of lawful and unlawful, the clarification through its eloquence that it is the speech of Allah, the clarification of the truth of prophethood, the clarification of the news of the former and latter peoples, or the clarification of the path to salvation from the doubts of the people of misguidance. Furthermore, the qualification of the Qur'an as 'mübin' is connected to reasons such as its being a miracle, the clarification within it of guidance, lawful and unlawful, and the explanation of the stories of the former peoples. It is stated that this verse was revealed when Jewish scholars suggested to the polytheist elders to ask about how the family of Jacob migrated from the Levant to Egypt and the nature of the story of Yusuf, and that the purpose of narrating the story in Arabic expressions was to enable understanding and acquisition of knowledge.

روي أن علماء اليهود قالوا لكبراء المشركين ، سلوا محمدا لم انتقل آل يعقوب من الشام إلى مصر ، وعن كيفية قصة يوسف ، فأنزل الله تعالى هذه الآية

According to Kurtubî, what is meant by 'al-Kitab al-Mübin' is the Qur'an, which clarifies its lawful and unlawful rulings, its guidance and blessing. Furthermore, according to one view, what is meant by 'tilka' (that) is these verses that were promised in the Torah; that is, 'tilka' here means 'hazihi' (this).

والمبين أي المبين بركته وخيره والمبين الحق من الباطل والحلال من الحرام وقصص الأنبياء ونبوة محمد صلى الله عليه وسلم

According to Ibn Kesîr, this expression points to the verses of the 'manifest Book', indicating that this Book is a clear and evident Book that distinguishes truth from falsehood, and guidance from misguidance. Furthermore, it is emphasized that this Book possesses a quality that reveals the realities of what has been and what will be.

أى هذه آيات القرآن المبين أي البين الواضح الجلي الذي يفصل بين الحق والباطل والغي والرشاد

Beydâvî states that the demonstrative 'tilka' refers to the verses of the surah itself and 'al-Kitab' is meant by them; he says that these verses are clear either in terms of being miraculous or in terms of their meanings being evident, or that they show to those who reflect that they come from Allah. Furthermore, according to one narration, he transmits that these verses were revealed when Jewish scholars suggested to the polytheist elders to ask the Prophet about how the family of Jacob migrated from the Levant to Egypt and the story of Yusuf. He explains that the word 'Qur'an' is originally a common noun and has become a proper noun for the whole by prevalence, and that the word 'arabiyyen' carries different grammatical parsing possibilities as a circumstantial state.

تلك إشارة إلى آيات السورة وهي المراد ب الكتاب، أي تلك الآيات آيات السورة الظاهر أمرها في الإعجاز أو الواضحة معانيها، أو المبينة لمن تدبرها أنها من عند الله
