Surah Al-Furqan, ayah 45

أَلَمۡ تَرَ إِلَىٰ رَبِّكَ كَيۡفَ مَدَّ ٱلظِّلَّ وَلَوۡ شَآءَ لَجَعَلَهُۥ سَاكِنٗا ثُمَّ جَعَلۡنَا ٱلشَّمۡسَ عَلَيۡهِ دَلِيلٗا ٤٥

Alam tara ilā rabbika kayfa maddaz-zilla walaw shā'a laja'alahū sākinan thumma ja'alnash-shamsa 'alayhi dalīlā

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.¹⁰²⁸
