Quran 20:113 Taha, ayah 113 of 135

وَكَذَٰلِكَ أَنزَلْنَـٰهُ قُرْءَانًا عَرَبِيًّا وَصَرَّفْنَا فِيهِ مِنَ ٱلْوَعِيدِ لَعَلَّهُمْ يَتَّقُونَ أَوْ يُحْدِثُ لَهُمْ ذِكْرًا ۝١١٣

20:113 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.
