وَمَا خَلَقْنَا السَّمَاء وَالْأَرْضَ وَمَا بَيْنَهُمَا لَاعِبِينَ
[21:16]
And We did not create the heaven and the earth and what is between them for sport.
Not for (idle) sport did We create the heavens and the earth and all that is between!
We created not the heaven and the earth and all that is between them in play.
