أَلَمْ تَرَ إِلَى رَبِّكَ كَيْفَ مَدَّ الظِّلَّ وَلَوْ شَاء لَجَعَلَهُ سَاكِنًا ثُمَّ جَعَلْنَا الشَّمْسَ عَلَيْهِ دَلِيلًا
﴿٤٥﴾
سورة الفرقان
(25/45) Have you not seen how your Lord extended the shade? And if He had willed, He would certainly have made it stationary. Then We have made the sun an indication (a guide) to it (shade).
Surah Al-Furqan
