Sad 38:27

وَمَا خَلَقْنَا ٱلسَّمَآءَ وَٱلْأَرْضَ وَمَا بَيْنَهُمَا بَـٰطِلًا ۚ ذَٰلِكَ ظَنُّ ٱلَّذِينَ كَفَرُوا۟ ۚ فَوَيْلٌ لِّلَّذِينَ كَفَرُوا۟ مِنَ ٱلنَّارِ

Wamā khalaqnā l-samāa wal-arḍa wamā baynahumā bāṭilan dhālika ẓannu alladhīna kafarū fawaylun lilladhīna kafarū mina l-nāri

And We did not create the heaven and the earth and that between them aimlessly. That is the assumption of those who disbelieve, so woe to those who disbelieve from the Fire.
