Qur'an 20:113

وَكَذَٰلِكَ أَنزَلْنَـٰهُ قُرْءَانًا عَرَبِيًّا وَصَرَّفْنَا فِيهِ مِنَ ٱلْوَعِيدِ لَعَلَّهُمْ يَتَّقُونَ أَوْ يُحْدِثُ لَهُمْ ذِكْرًا

Thus we have revealed it as a Lecture in Arabic, and have displayed therein certain threats, that peradventure they may keep from evil or that it may cause them to take heed.
