Surah Ar-Ra'd (The Thunder), Verse 15

وَلِلّٰهِ یَسْجُدُ مَنْ فِی السَّمٰوٰتِ وَالْاَرْضِ طَوْعًا وَّكَرْهًا وَّظِلٰلُهُمْ بِالْغُدُوِّ وَالْاٰصَالِ ۟

Wa lillaahi yasjudu man fis samaawaati wal ardi taw 'anw wa karhanw wa zilaaluhum bilghuduwwi wal aasaal

“Whatever beings there are in the heavens and the earth do prostrate themselves to Allah (Acknowledging subjection),- with good-will or in spite of themselves: so do their shadows in the morning and evenings.”

Quran 13:15 (Yusuf Ali Translation)
