لَا الشَّمْسُ يَنبَغِي لَهَا أَن تُدْرِكَ الْقَمَرَ وَلَا اللَّيْلُ سَابِقُ النَّهَارِ ۚ وَكُلٌّ فِي فَلَكٍ يَسْبَحُونَ
It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. [Yasin 36:40]
وَ كُ لٌّ فِ ي فَ لَكٍ يَ سْبَحُونَ
And all in swimming they (are) floating [in orbit]
NOTE: See the letters Orbitting/floating around the letter ‘Ya’
In this ayah Allah (SWT) is speaking about how the sun and the moon are in orbit. Look at the letters inred, brown and green; they are all floating around the letter in orange. The next word begins with the letter ya [YaSbah], which is referring to Floating (TaSbeeh is from the same root). SubhanAllah!
The letters are Floating around one another, since the concept being discussed is Orbit. Only the speech of Allah can be perfect in style and content!
