AL AHQAAF (BUKIT-BUKIT PASIR) — 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.
