(Qaaf) 50 : 38
وَلَقَدْ خَلَقْنَا السَّمَاوَاتِ وَالْأَرْضَ وَمَا بَيْنَهُمَا فِي سِتَّةِ أَيَّامٍ وَمَا مَسَّنَا مِنْ لُغُوبٍ

And surely We have created the Heavens, Earth, and whatever between them in six days, and no tiredness is affected Us due to it.

See explanation 25: 58-60; 40: 57-58; and 50:15.
