25. Al-Furqan (The Criterion, The Standard)

Surah: 25   Aya: 45

45. Alam tara ila rabbika kayfa madda alththilla walaw shaa lajaAAalahu sakinan thumma jaAAalna alshshamsa AAalayhi daleelan
  

  Translation

45. Have you not seen how your Lord spread the shadow. If He willed, He could have made it still then We have made the sun its guide [i.e. after the sunrise, it (the shadow) squeezes and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sun light, there would have been no shadow].
