Quran 20:113 from Surah Taa-Haa on Divine Marvels.
وَكَذَٰلِكَ أَنزَلۡنَٰهُ قُرۡءَانًا عَرَبِيّٗا وَصَرَّفۡنَا فِيهِ مِنَ ٱلۡوَعِيدِ لَعَلَّهُمۡ يَتَّقُونَ أَوۡ يُحۡدِثُ لَهُمۡ ذِكۡرٗا
English translation: And thus We have sent it down (the) Quran (in) Arabic and We have explained in it of the warnings that they may fear or it may cause [for] them remembrance
Transliteration: wakadhalika anzalnahu qur'anan arabiyyan wasarrafna fihi mina al-wa'idi la'allahum yattaquna aw yuh'dithu lahum dhik'ran
