An-Nahl - 16:48

أَوَ لَمْ يَرَوْاْ إِلَى مَا خَلَقَ اللّهُ مِن شَيْءٍ يَتَفَيَّأُ ظِلاَلُهُ عَنِ الْيَمِينِ وَالْشَّمَآئِلِ سُجَّدًا لِلّهِ وَهُمْ دَاخِرُونَ
[16:48]
Do they not consider every thing that Allah has created? Its (very) shadows return from right and left, making obeisance to Allah while they are in utter abasement.
Do they not look at Allah's creation, (even) among (inanimate) things,- How their (very) shadows turn round, from the right and the left, prostrating themselves to Allah, and that in the humblest manner?
Have they not observed all things that Allah hath created, how their shadows incline to the right and to the left, making prostration unto Allah, and they are lowly?
