وَمِن قَبْلِهِ كِتَابُ مُوسَىٰ إِمَامًا وَرَحْمَةً ۚ وَهَٰذَا كِتَابٌ مُّصَدِّقٌ لِّسَانًا عَرَبِيًّا لِّيُنذِرَ الَّذِينَ ظَلَمُوا وَبُشْرَىٰ لِلْمُحْسِنِينَ (12)
(46:12) Yet before this the Book was revealed to Moses as a guide and a mercy. This Book, which confirms it, is in the Arabic tongue to warn the wrong-doers *17 and to give good tidings to those who do good.
*17) "To warn the wrongdoers :" To warn of the evil end those who are being unjust to themselves and to the truth itself by disbelieving in Allah and serving others than Allah, and are involved because of this deviation of theirs in the evils of morals and deeds, which have filled human society with every kind of wickedness and injustice.
