between the two mountains. That is, We made roads between the mountains so that they might find their way to their destinations. “As pathways” explains “broad mountain passes,” “so that they might be guided.”
“And We made the sky a protected canopy, yet they turn away from its signs. (32) And He is the One who created the night and the day, the sun and the moon—each floating in an orbit. (33)”
“And We made the sky a protected canopy”: protected from falling down. Evidence for this is His saying, Exalted is He: “He holds the sky back from falling upon the earth except by His permission” (al-Hajj 22:65). It was also said: protected from the devils by meteors, as indicated by His saying, Exalted is He: “And We have protected it from every accursed devil” (al-Hijr 15:17). “Yet they”—that is, the disbelievers—“turn away from its signs”: from what Allah has created in it of the sun, moon, stars, and other things. “They turn away”: they neither reflect upon them nor take heed from them.
“And He is the One who created the night and the day, the sun and the moon—each floating in an orbit”: that is, they move and travel swiftly, like a swimmer in water. He said, “floating,” rather than using the form ordinarily used for inanimate things, because He attributed to them actions of rational beings—movement and swimming—so they were referred to with the form used for rational beings.
An orbit is the course that contains the stars. In Arabic usage, it refers to every circular thing; its plural is orbits. From this is the spindle whorl.
Al-Hasan said: “The orbit is a millstone, like the whorl of a spindle.” He meant that the region in which the stars move is circular, like the rotation of a millstone.
Others said: The orbit is the heaven in which that celestial body is found. Thus, every celestial body moves in the heaven apportioned for it. This is the meaning of Qatadah’s statement.
Al-Kalbi (1) said: The orbit is the circularity of the sky.
Others said: The orbit is a restrained wave beneath the sky, in which the sun, moon, and stars move (2).
