أَلَمْ تَرَ إِلَىٰ رَبِّكَ كَيْفَ مَدَّ ٱلظِّلَّ وَلَوْ شَآءَ لَجَعَلَهُۥ سَاكِنًا ثُمَّ جَعَلْنَا ٱلشَّمْسَ عَلَيْهِ دَلِيلًا
alam tara ilā rabbika kayfa madda l-ẓila walaw shāa lajaʿalahu sākinan thumma jaʿalnā l-shamsa ʿalayhi dalīlan
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.
— Saheeh International
Do you not see how your Lord lengthens the shade? If He had willed, He could have made it stand still- We made the sun its indicator-
— M. A. S. Abdel Haleem
Have you not seen how your Lord spread the shadow. If He willed, He could have made it still - But We have made the sun its guide (i.e. after the sunrise, the shadow shrinks and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sunlight, there would have been no shadow).
— Muhammad Muhsin Khan & Muhammad Taqi-ud-Din al-Hilali
