وَجَعَلَ فِيهَا رَوَٰسِىَ مِن فَوْقِهَا وَبَـٰرَكَ فِيهَا وَقَدَّرَ فِيهَآ أَقْوَٰتَهَا فِىٓ أَرْبَعَةِ أَيَّامٍ سَوَآءً لِّلسَّآئِلِينَ

Nearby ayahs help place verse 41:10 in sequence and meaning.
إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ لَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ
Indeed, those who believe and do righteous deeds - for them is a reward uninterrupted.
۞ قُلْ أَئِنَّكُمْ لَتَكْفُرُونَ بِٱلَّذِى خَلَقَ ٱلْأَرْضَ فِى يَوْمَيْنِ وَتَجْعَلُونَ لَهُۥٓ أَندَادًا ۚ ذَٰلِكَ رَبُّ ٱلْعَـٰلَمِينَ
Say, "Do you indeed disbelieve in He who created the earth in two days and attribute to Him equals? That is the Lord of the worlds."
ثُمَّ ٱسْتَوَىٰٓ إِلَى ٱلسَّمَآءِ وَهِىَ دُخَانٌ فَقَالَ لَهَا وَلِلْأَرْضِ ٱئْتِيَا طَوْعًا أَوْ كَرْهًا قَالَتَآ أَتَيْنَا طَآئِعِينَ
Then He directed Himself to the heaven while it was smoke and said to it and to the earth, "Come [into being], willingly or by compulsion." They said, "We have come willingly."
فَقَضَىٰهُنَّ سَبْعَ سَمَـٰوَاتٍ فِى يَوْمَيْنِ وَأَوْحَىٰ فِى كُلِّ سَمَآءٍ أَمْرَهَا ۚ وَزَيَّنَّا ٱلسَّمَآءَ ٱلدُّنْيَا بِمَصَـٰبِيحَ وَحِفْظًا ۚ ذَٰلِكَ تَقْدِيرُ ٱلْعَزِيزِ ٱلْعَلِيمِ
And He completed them as seven heavens within two days and inspired in each heaven its command. And We adorned the nearest heaven with lamps and as protection. That is the determination of the Exalted in Might, the Knowing.
