وَمَا خَلَقْنَا السَّمَاء وَالْأَرْضَ وَمَا بَيْنَهُمَا لَاعِبِينَ

And We did not create the heaven and earth and that between them in play.

{ وما خلقنا السماء والأرض وما بينهما لاعبين } عابثين بل دالين على قدرتنا ونافعين عبادنا .

{And We did not create the heaven and the earth and what is between them in play} but rather to demonstrate Our power and to benefit Our servants.
