Verš 20:6

a vše, co na nebesích je a na zemi, mezi nimi i pod povrchem země, Jemu náleží.

Tafsir al-Jalalayn

to Him belongs whatever is in the heavens and whatever is in the earth and whatever is between them, of creatures, and whatever is beneath the soil (al-tharā, is moist earth) meaning [whatever is beneath] the seven earths, since these lie beneath it.
