Quran Al-Furqan 25:45
أَلَمۡ تَرَ إِلَىٰ رَبِّكَ كَيۡفَ مَدَّ ٱلظِّلَّ وَلَوۡ شَآءَ لَجَعَلَهُۥ سَاكِنٗا ثُمَّ جَعَلۡنَا ٱلشَّمۡسَ عَلَيۡهِ دَلِيلٗا ٤٥
Translation
Have you not considered your Lord - how He extends the shadow, and if He willed, He could have made it stationary? Then We made the sun for it an indication.
