وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦٓ إِذْ قَالُوا۟ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ بَشَرٍ مِّن شَىْءٍ ۗ قُلْ مَنْ أَنزَلَ ٱلْكِتَـٰبَ ٱلَّذِى جَآءَ بِهِۦ مُوسَىٰ نُورًا وَهُدًى لِّلنَّاسِ ۖ تَجْعَلُونَهُۥ قَرَاطِيسَ تُبْدُونَهَا وَتُخْفُونَ كَثِيرًا ۖ وَعُلِّمْتُم مَّا لَمْ تَعْلَمُوٓا۟ أَنتُمْ وَلَآ ءَابَآؤُكُمْ ۖ قُلِ ٱللَّهُ ۖ ثُمَّ ذَرْهُمْ فِى خَوْضِهِمْ يَلْعَبُونَ

They have no grasp of God’s true measure when they say, ‘God has sent nothing down to a mere mortal.’ Say, ‘Who was it who sent down the Scripture, which Moses brought as a light and a guide to people, which you made into separate sheets, showing some but hiding many? You were taught things that neither you nor your forefathers had known.’ Say, ‘God [sent it down],’ then leave them engrossed in their vain talk.
They (the Jews, Quraish pagans, idolaters) did not estimate Allâh with an estimation due to Him when they said: "Nothing did Allâh send down to any human being (by revelation)." Say (O Muhammad صلى الله عليه وسلم): "Who then sent down the Book which Mûsâ (Moses) brought, a light and a guidance to mankind which you (the Jews) have made into (separate) papersheets, disclosing (some of it) and concealing much. And you (believers in Allâh and His Messenger Muhammad صلى الله عليه وسلم) were taught (through the Qur’ân) that which neither you nor your fathers knew." Say: "Allâh (sent it down)." Then leave them to play in their vain discussions. (Tafsir Al-Qurtubî).
