Luqman 31:10
The verse lines up two verbs side by side: the sky was raised "bi-ghayri ʿamadin tarawnahā" (without pillars you can see); upon the earth "rawāsī" (weighty, fixed structures) were cast "an tamīda bikum" (lest it sway under you).
خَلَقَ ٱلسَّمَـٰوَٰتِ بِغَيْرِ عَمَدٍ تَرَوْنَهَا ۖ وَأَلْقَىٰ فِى ٱلْأَرْضِ رَوَٰسِىَ أَن تَمِيدَ بِكُمْ وَبَثَّ فِيهَا مِن كُلِّ دَآبَّةٍ ۚ وَأَنزَلْنَا مِنَ ٱلسَّمَآءِ مَآءً فَأَنۢبَتْنَا فِيهَا مِن كُلِّ زَوْجٍ كَرِيمٍ
He created the heavens without pillars that you can see, and placed stabilizers on earth lest it shifts with you, and scattered throughout it all kinds of creatures. And from the sky We sent down water, and caused to grow therein of every noble pair
Luqman 31:10 · Translation: talal-itani
Image
An unseen support (the sky) and a seen weight (the mountain) are set within the same sentence as two faces of the same order.
Observation
Classical tafsīr reads "bi-ghayri ʿamadin tarawnahā" in two ways: (1) without visible pillars; (2) with supports the eye cannot see. This second reading does not say the same thing as modern physics; but it shares the same image: celestial bodies are bound to one another without a visible prop, through mutual gravitation. The sense of "rawāsī" as "weight, anchored mass" is read in classical tafsīr as the holding of the earth in balance; in earth morphology, the stability that great masses give to the region they occupy can be set alongside the image of the verse — though this is not a one-to-one scientific explanation, but a point where the observational language of the verse meets modern observation.
Exegesis
Elmalılı Hamdi Yazır reads "bi-ghayri ʿamadin tarawnahā" as "unseen supports" and conveys that this reading has been accepted in the classical tafsīr tradition. Al-Rāzī draws attention to the verse joining two elements — sky and earth — within the same order: above, an unseen holder; below, a seen fixer. The verse goes on to speak of waters and living creatures — the order is described by the same hand not only in masses but in life itself.
