quran:46:12 –

And before it was the scripture of Moses to lead and as a mercy. And this is a confirming Book in an Arabic tongue to warn those who have wronged and as good tidings to the doers of good.  

Yet before it, that is, ˹before˺ the Qur’ān, ˹there was˺ the Book of Moses, that is, the Torah, as a guidepost and a mercy, for those who believed in it (imāman wa-rahmatan are two circumstantial qualifiers) and this, Qur’ān, is a Book that confirms, scriptures before it, in the Arabic tongue (lisānan ‘arabiyyan is a circumstantial qualifier referring to the subject of musaddiqun, ‘that confirms’) to warn those who do wrong, the idolaters of Mecca, and, it is, good tidings for the virtuous, the believers.
القرآن:٤٦:١٢ –

وَمِنْ قَبْلِهِ كِتَابُ مُوسَىٰ إِمَامًا وَرَحْمَةً ۚ وَهَٰذَا كِتَابٌ مُصَدِّقٌ لِسَانًا عَرَبِيًّا لِيُنْذِرَ الَّذِينَ ظَلَمُوا وَبُشْرَىٰ لِلْمُحْسِنِينَ  

{ومن قبله} أي القرآن {كتاب موسى} أي التوراة {إماما ورحمة} للمؤمنين به حالان {وهذا} أي القرآن {كتاب مصدق} للكتب قبله {لسانا عربيا} قال لمن الضمير في مصدق {لينذر الذين ظلموا} مشركي مكة {و} هو {بشرى للمحسنين} المؤمنين.
