سورة النحل

Imam Kazim (peace be upon him): Hisham ibn al-Hakam said: Imam Kazim (peace be upon him) said to me: "O Hisham! Allah has made these things a proof and evidence for knowing Him, because [such creations] certainly have a Regulator, so He said: وَ سَخَّرَ لَکُمُ اللَّیْلَ وَ النَّهارَ وَ الشَّمْسَ وَ الْقَمَرَ وَ النُّجُومُ مُسَخَّراتٌ بِأَمْرِهِ إِنَّ فِی ذلِکَ لَآیاتٍ لِقَوْمٍ یَعْقِلُونَ [And He has made subservient for you the night and the day and the sun and the moon, and the stars are made subservient by His commandment; most surely there are signs in this for a people who ponder]."

The Messenger of Allah (peace be upon him and his family): Imam Sadiq (peace be upon him) narrated from his father, and [his father] from his grandfather: "The Messenger of Allah (peace be upon him and his family) said: Allah did not create any creation without appointing another creature as its commander and giving it dominance over it. So it is that when Allah created the seas in the sky, those seas grew proud and surged and said: 'What thing can overcome us?' Then Allah created [the planets and] the celestial sphere, and by means of it He set the seas in motion and humbled them. Then the earth grew proud and said: 'What thing can overcome me?' Then Allah created the mountains and fixed them upon the back of the earth like pegs, so that whatever is on the earth would remain at rest [and not tremble]; and so the earth was humbled and became still."
