Indeed, We have made it an Arabic Qur'an that you might understand. (43:3)

Almuntakhab Fi Tafsir Alquran Alkarim

A Book, We have made in Arabic literary form that you may hopefully comprehend its inimitability and employ the faculty of reason in forming conclusions

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(43:3) verily We have made it an Arabic Qur'an that you may understand. *1

Indeed, We have made it an Arabic Qur'an that you might understand. meaning

*1) The object of taking an oath by the Qur'an is to impress this fact: "We are the Author of this Book and not Muhammad (upon whom be Allah's peace)," and the attribute of the Qur'an chosen for the oath is that it is a "lucid Book". To swear by the Qur'an itself with its this attribute in order to impress that the Qur'an is Divine Word by itself implies this: "O people, this is an open Book before you. Read it intelligently. Its clear and un-ambiguous themes, its language and literary style, its teaching which distinguishes the truth from falsehood, all arc testifying to the fact that none but the Lord of the Universe could be its Author. " Then the sentence: '"We have made it an Arabic Qur'an so that you may understand it." has two meanings:(1) "It is not in any foreign tongue but in your own language; therefore, you can have no difficulty in assessing its value and worth. Had it been in a non-Arabic language, you could have offered the excuse that you could not determine its being Divine, or otherwise, for you did not understand it. But you cannot offer this excuse about this Arabic Qur'an. Its each word is clear to you: its each passage and discourse, both in language and in theme, is plain for you. Now you may see it for yourself whether this could be the word of Muhammad (upon whom be Allah's peace) or of some other Arab." (2) "We have sent this Book in Arabic because We are addressing the Arabs, who can only understand an Arabic Qur'an. The person who disregards this expressly rational ground for sending down the Qur'an in Arabic and regards it as the word of Muhammad (upon whom be Allah's peace) instead of Divine Word only because Muhammad's mother tongue is also Arabic, commits a grave injustice. " (To understand this second meaning, please see Surah Ha-Mim As-Sajdah: 44 and its E.N.'s).
