Refutation of disbelief and polytheism

ثُمَّ خَلَقْنَا ٱلنُّطْفَةَ عَلَقَةً فَخَلَقْنَا ٱلْعَلَقَةَ مُضْغَةً فَخَلَقْنَا ٱلْمُضْغَةَ عِظَـٰمًا فَكَسَوْنَا ٱلْعِظَـٰمَ لَحْمًا ثُمَّ أَنشَأْنَـٰهُ خَلْقًا ءَاخَرَ ۚ فَتَبَارَكَ ٱللَّهُ أَحْسَنُ ٱلْخَـٰلِقِينَ

Then We made the sperm-drop into a clinging clot, and We made the clot into a lump [of flesh], and We made [from] the lump, bones, and We covered the bones with flesh; then We developed him into another creation. So blessed is Allāh, the best of creators.

أَفَلَمْ يَنظُرُوٓا۟ إِلَى ٱلسَّمَآءِ فَوْقَهُمْ كَيْفَ بَنَيْنَـٰهَا وَزَيَّنَّـٰهَا وَمَا لَهَا مِن فُرُوجٍ

Have they not looked at the heaven above them - how We structured it and adorned it and [how] it has no rifts?
