Allah is the One who created seven heavens and likewise from the earth, He sends down the commands in between them in order to know that indeed Allah is capable upon each and everything, and indeed He is acquainted with each and every Knowledge.
It is mentioned about seven heavens in verses 2: 29; 23: 86; 41: 12; and 67: 3, but in this verse only it is mentioned about the seven earths by saying ‘likewise from the earth’. The Three Time Knower Allah who has already decided whatever and whenever anything should happen in the seven heavens, earth, and in between them is also acquainted with all of them. All these are created and explained in order to fulfil the aim of life by identifying Allah utilising the Three Time Knowledge Adhikr which explains each and everything. See explanation 20: 5-6; 25: 59-60; and 35: 15-17.
