Surah Az-Zukhruf, Ayah 6

Which was revealed in Makkah

بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ

In the name of Allah, the Beneficent, the Merciful

حـم - تَنزِيلُ الْكِتَـبِ مِنَ اللَّهِ الْعَزِيزِ الْعَلِيمِ

(Ha-Mim. By the manifest Book.) means, plain and clear in both wording and meaning, because it was revealed in the language of the Arabs, which is the most eloquent language for communication among people. Allah says:

إِنَّا جَعَلْنَـهُ

(Verily, We have made it) meaning, revealed it,

قُرْءَاناً عَرَبِيّاً

(a Qur'an in Arabic) meaning, in the language of the Arabs, eloquent and clear;

لَعَلَّكُمْ تَعْقِلُونَ

(that you may be able to understand.) means, that you may understand it and ponder its meanings. This is like the Ayah:

A Preacher must not give up his preaching due to disappointment

أَفَنَضْرِ‌بُ عَنكُمُ الذِّكْرَ‌ صَفْحًا أَن كُنتُمْ قَوْمًا مُّسْرِ‌فِينَ (Shall we remove the advice away from you because you are a transgressing people? - 43:5) The meaning is that We will not give up advising you through the Qur'an, no matter how rebellious and disobedient you may become. This tells us that the person who is engaged in preaching and inviting others towards Islam should carry the message to everybody; he must not give up preaching to some people or any group simply because they are non-believers, highly irreligious, sinners and transgressors.

The Original Book, or the Mother of Book (ummul kitab), refers to the preserved tablet (lawh mahfuz), which is with God. On this tablet, God Almighty has an imprint of the true religion, which He requires human beings to follow. This true religion, revealed to numerous prophets in various languages, was revealed to the Last of the Prophets in Arabic. Today, it is only this Arabic Quran which represents the true religion of God. It is now the responsibility of the bearers of the Quran to have it translated into every language and make it available to all the nations of the world, so that this religion may be understood by all other people, as it was understood by the Arabs. These sublime scriptures, being full of wisdom, are in themselves proof of their being the Book of God. The language of the Quran and its contents do justice to the Majesty of God with the utmost exactitude. Had the Quran been couched in the words of human beings, it would not have possessed the extraordinary glory which it possesses till today.
