AL AHQAAF — Ayat 12

وَمِن قَبْلِهِ كِتَابُ مُوسَى إِمَامًا وَرَحْمَةً وَهَذَا كِتَابٌ مُّصَدِّقٌ لِّسَانًا عَرَبِيًّا لِّيُنذِرَ الَّذِينَ ظَلَمُوا وَبُشْرَى لِلْمُحْسِنِينَ

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.
