Surah 13:2
"(It is) God who raised up the heavens without pillars that you (can) see. Then He mounted the throne, and subjected the sun and the moon, each one running (its course) for an appointed time. He directs the (whole) affair. He makes the signs distinct, so that you may be certain of the meeting with your Lord."
Sky is a Tent/Dome
A common myth at the time of the Quran's composition was that the sky or heavens were held up with pillars. Many Bedouin people living in Arabia imagined the sky as a large tent covering, similar to the tents they used. The author repeats this myth by describing the sky as being "raised" above the earth.
