We have rendered it an Arabic Quran, that you may understand.*
إِنّا جَعَلنٰهُ قُرءٰنًا عَرَبِيًّا لَعَلَّكُم تَعقِلونَ
innaa ja’alnaahu Quraanan ‘Arabiyyal la’allakum ta’qiloon
*43:3 Arabic is the most efficient language, especially in expressing commandments, statutes and exacting laws. Hence the revelation of the Quran in Arabic for the clear understanding of all peoples, regardless of their tongues. See Appendix 4 for the details.
