Surah Taha, ayah 113

وَكَذَٰلِكَ أَنزَلۡنَٰهُ قُرۡءَانًا عَرَبِيّٗا وَصَرَّفۡنَا فِيهِ مِنَ ٱلۡوَعِيدِ لَعَلَّهُمۡ يَتَّقُونَ أَوۡ يُحۡدِثُ لَهُمۡ ذِكۡرٗا ١١٣

Wakadhālika anzalnāhu qur'ānan 'arabiyyan wasarrafnā fīhi minal-wa'īdi la'allahum yattaqūna aw yuhdithu lahum dhikrā

And thus We have sent it down as an Arabic Qur’ān⁸⁶⁰ and have diversified therein the warnings that perhaps they will avoid [sin] or it would cause them remembrance.
