And it was not [possible] for this Qur'an to be produced by (10:37)

Almuntakhab Fi Tafsir Alquran Alkarim

Nor could this Quran be contrived by anyone even if he is of singular ingenuity. Its inimitability, guidance and precision betoken its divine nature and exclude all else besides Allah. It corroborates and authoritatively validates all the divine Books revealed before it in time and serves as an excellent interpretation expounding all the statutes and ordinances past and present revealed to all intelligent creatures and exacts obedience from the whole. It is undoubtedly a Revelation emphatically revealed by Allah, the Creator of the universe and of the world-to-come

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(10:37) And this Qur'an is such that it could not be composed by any unless it be revealed from Allah. It is a confirmation of the revelation made before it and a detailed exposition of the Book. *45 Beyond doubt it is from the Lord of the universe.

*45).The statement that it is 'a confirmation of the revelation made before it' underscores that the Qur'an lays no claim of introducing anything novel, of coming forth with any innovation at variance with the fundamental teachings already communicated to man through the Prophets (peace be on them). The Qur'anic claim merely consists of confirming and authenticating those teachings. Had the Qur'an been the product of the imagination of the founder of an altogether new religion, the outcome of a creative brain, it would have borne traces of novelty in order to emphasize its distinctiveness.
The second part of the statement, namely that the Qur'an is a 'detailed exposition of the Book' is equally significant. What this means is that the Qur'an elaborates those fundamental teachings which constitute the core and essence of all the scriptures (al-Kitab); that is, those teachings which have been sufficiently elucidated in the Qur'an so that they might be grasped by people and penetrate their hearts; and additionally, it has been shown how those teachings could be applied to practical life.

اور یہ قرآن وہ چیز نہیں ہے جو اللہ کی وحی و تعلیم کے بغیر تصنیف کر لیا جائے بلکہ یہ تو جو کچھ پہلے آ چکا تھا اس کی تصدیق اور الکتاب کی تفصیل ہے اِس میں کوئی شک نہیں کہ یہ فرمانروائے کائنات کی طرف سے ہے
