[It is] an Arabic Qur'an, without any deviance that they might become righteous.

His saying: qurʾānan ʿarabiyyan (an Arabic Qurʾān). The Exalted, praised be His mention, says: Indeed, We have set forth for mankind in this Qurʾān every kind of parable — an Arabic Qurʾān ghayra dhī ʿiwaj (without crookedness), that is to say: without obscurity.
As Muḥammad ibn ʿAmr related to me, saying: Abū ʿĀṣim related to us, saying: ʿĪsā related to us; and al-Ḥārith related to me, saying: al-Ḥasan related to us, saying: Warqāʾ related to us — both of them — on the authority of Ibn Abī Najīḥ, on the authority of Mujāhid: qurʾānan ʿarabiyyan ghayra dhī ʿiwaj (an Arabic Qurʾān without crookedness): without obscurity.
The accusative in His saying qurʾānan ʿarabiyyan stands on the basis of the circumstantial qualifier (ḥāl) derived from His saying "this Qurʾān," because "the Qurʾān" is a determinate noun (maʿrifa), whereas His saying qurʾānan ʿarabiyyan is indeterminate (nakira).
His saying: laʿallahum yattaqūn (that they might be God-fearing). He says: We made it an Arabic Qurʾān, since they were Arabs, so that they might understand the admonitions contained therein, until they would guard themselves against that which Allah has warned them of therein concerning His power and His might, so that they would turn to His worship and to holding the Godhead as one for Him alone, and would declare themselves free of the rivals and the gods.
