Quran 25:45 from Surah Al-Furqaan on Divine Marvels.
أَلَمۡ تَرَ إِلَىٰ رَبِّكَ كَيۡفَ مَدَّ ٱلظِّلَّ وَلَوۡ شَآءَ لَجَعَلَهُۥ سَاكِنٗا ثُمَّ جَعَلۡنَا ٱلشَّمۡسَ عَلَيۡهِ دَلِيلٗا
English translation: Do you not see [to] your Lord how He extends the shadow And if He willed surely He (could) have made it stationary Then We made the sun for it an indication
Transliteration: alam tara ila rabbika kayfa madda al-zila walaw shaa laja'alahu sakinan thumma ja'alna al-shamsa alayhi dalilan
