﴿ وَٱلْأَرْضَ مَدَدْنَٰهَا وَأَلْقَيْنَا فِيهَا رَوَٰسِىَ وَأَنۢبَتْنَا فِيهَا مِن كُلِّ زَوْجٍۭ بَهِيجٍۢ ﴾

“And the earth - We have spread it wide, and set upon it mountains firm, and caused it to bring forth plants of all beauteous kinds,”

And the earth wa’l-arda is a supplement to the position of the words ilā l-samā’i ‘at the heaven’ how We have spread it out how We have rolled it across the face of the water and cast in it firm mountains to fix it in place and caused every delightful kind every delightful specimen causing delight by its very beauty to grow in it
