And of his signs is the creation of the heavens and earth and what He has dispersed throughout them of creatures. And He, for gathering them when He wills, is competent.
According to Muhammad Asad, the term “Heavens and Earth” denotes:
‘Lit., “in both”. In the Qur’an, the expression “the heavens and the earth” invariably denotes the universe in its entirety.’ (The Message of the Quran, pg. 950, note #33)
“It is Allah who has created the seven heavens and a like number of earths. His commandments are sent between them, so that you would know that Allah has power over all things and that His knowledge encompasses all” (The HolyKoran 65:☐2).
As written by Dr. Anisur Rahman:
“Hence, if we pay attention to the above Noble verses, it is very clear that the Glorious Koran says that the Earth is not the only unique and the only one in this Universe, and that, living things are also not only exclusive to the Earth. Rather, innumerable earths and living beings (seven earths may just allegorically means huge numbers) are dispersed in this gigantic Universe.”
