وَلِلَّهِ يَسْجُدُ مَنْ فِي السَّمَاوَاتِ وَالْأَرْضِ طَوْعًا وَكَرْهًا وَظِلَالُهُمْ بِالْغُدُوِّ وَالْآصَالِ ۩ 15
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.
