quran:50:38 –

And We did certainly create the heavens and earth and what is between them in six days, and there touched Us no weariness.  

And verily We created the heavens and the earth, and all that is between them, in six days, the first of which was Sunday and the last of which was Friday, and no weariness, no fatigue, touched Us: this was revealed as a refutation of the Jews’ claim that God rested on the Saturday and lay down upon the Throne. The preclusion of weariness in His case is ˹absolute˺ on account of His transcending of the attributes of creatures and the non-existence of any contiguity between Him and other ˹beings˺: His command, when He wills a thing, is just to say to it ‘Be’, and it is ˹Q. 36:82˺.
القرآن:٥٠:٣٨ –

وَلَقَدْ خَلَقْنَا السَّمَاوَاتِ وَالْأَرْضَ وَمَا بَيْنَهُمَا فِي سِتَّةِ أَيَّامٍ وَمَا مَسَّنَا مِنْ لُغُوبٍ  

(ولقد خلقنا السماوات والأرض وما بينهما في ستة أيام) أولها الأحد وآخرها الجمعة (وما مسنا من لغوب) تعب، نزل ردا على اليهود في قولهم: إن الله استراح يوم السبت وانتفاء التعب عنه لتنزهه تعالى عن صفات المخلوقين ولعدم المماثلة بينه وبين غيره "" إنما أمره إذا أراد شيئا أن يقول له كن فيكون "".
