There are three reasons why the Quran was revealed in Arabic:
- Prophet Mohammed, peace be upon him, was Arab and his mother tongue was Arabic. So if the revelation was in another language, it would have been hard for him to convey the message to his people in an efficient way.
- Arabic is a rich, eloquent language. The Arab poets at that time were competing to show up the deep meaning and complexity of their masterpieces . The Quran was revealed in the richest language that had unique nature.It was a miracle both in grammar and eloquence.
- Quran was the last message sent in Arabic from Allah to Prophet Mohammed to guide his people, the Arabs, to Islam. The message of Islam started from there before reaching other countries. Yet, Allah’s previous revelations to prophets before Prophet Mohammed were sent in their own people’s mother tongues. This clearly shows the importance of the message location to determine what language is being used.
