The phenomenon of reflection in the Qur'an

وَلِلَّهِ يَسْجُدُ مَن فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ طَوْعًۭا وَكَرْهًۭا وَظِلَٰلُهُم بِٱلْغُدُوِّ وَٱلْءَاصَالِ ۩

Whatever beings there are in the heavens and the earth do prostrate themselves to Allah (Acknowledging subjection),- with good-will or in spite of themselves: so do their shadows in the morning and evenings.

أَوَلَمْ يَرَوْا۟ إِلَىٰ مَا خَلَقَ ٱللَّهُ مِن شَىْءٍۢ يَتَفَيَّؤُا۟ ظِلَٰلُهُۥ عَنِ ٱلْيَمِينِ وَٱلشَّمَآئِلِ سُجَّدًۭا لِّلَّهِ وَهُمْ دَٰخِرُونَ

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?

وَٱللَّهُ جَعَلَ لَكُم مِّمَّا خَلَقَ ظِلَٰلًۭا وَجَعَلَ لَكُم مِّنَ ٱلْجِبَالِ أَكْنَٰنًۭا وَجَعَلَ لَكُمْ سَرَٰبِيلَ تَقِيكُمُ ٱلْحَرَّ وَسَرَٰبِيلَ تَقِيكُم بَأْسَكُمْ ۚ كَذَٰلِكَ يُتِمُّ نِعْمَتَهُۥ عَلَيْكُمْ لَعَلَّكُمْ تُسْلِمُونَ

It is Allah Who made out of the things He created, some things to give you shade; of the hills He made some for your shelter; He made you garments to protect you from heat, and coats of mail to protect you from your (mutual) violence. Thus does He complete His favours on you, that ye may bow to His Will (in Islam).

أَلَمْ تَرَ إِلَىٰ رَبِّكَ كَيْفَ مَدَّ ٱلظِّلَّ وَلَوْ شَآءَ لَجَعَلَهُۥ سَاكِنًۭا ثُمَّ جَعَلْنَا ٱلشَّمْسَ عَلَيْهِ دَلِيلًۭا

Hast thou not turned thy vision to thy Lord?- How He doth prolong the shadow! If He willed, He could make it stationary! then do We make the sun its guide;

ثُمَّ قَبَضْنَٰهُ إِلَيْنَا قَبْضًۭا يَسِيرًۭا

Then We draw it in towards Ourselves,- a contraction by easy stages.
