وكذلك أوحينا إليك قرآنا عربيا لتنذر أم القرى ومن حولها وتنذر يوم (42:7) بالانجليزي

(42:7) And thus did We reveal this Arabic Qur'an *8 to you that you may warn the people of the Mother of Cities (to wit, Makkah) and those who dwell around it; *9 and warn them of the Day of Gathering *10 concerning which there is no doubt: whereon some will be in Paradise, and some in the Blazing Fire.

Tafseer Abu-al-A'la Maududi

Page 483 English Traditional

*8) The same thing which had been said in the beginning of the discourse has been said again with greater emphasis, and by making mention of the "Arabic Qur'an", the listeners have been warned to the effect: "The Qur'an is not in any foreign language but in your own language: you can understand it yourself directly; study its themes and see for yourself that the pure and selfless guidance that is being given in it can be from none other than the Lord of the Universe."
*9) That is, "Arouse them from slumber and warn them that there is nothing but destruction in store for them in consequence of the errors of morality and conduct in which they are involved and of the perverse principle on which they have ordered their individual and collective lives."
*10) That is, "Tell them also that this destruction is not confined only to this world but the Day has to come when Allah will gather together alI mankind and subject them to accountability. Even if a person escaped the evil consequences of his deviation and wickedness in the world, there will be no chance of his escape on that Day, and highly unfortunate is he, who is doomed to a tragic fate both in this world and in the Hereafter."
