أَلَمْ تَرَ أَنَّ اللَّهَ سَخَّرَ لَكُم مَّا فِي الْأَرْضِ وَالْفُلْكَ تَجْرِي فِي الْبَحْرِ بِأَمْرِهِ وَيُمْسِكُ السَّمَاءَ أَن تَقَعَ عَلَى الْأَرْضِ إِلَّا بِإِذْنِهِ ۗ إِنَّ اللَّهَ بِالنَّاسِ لَرَءُوفٌ رَّحِيمٌ (65)
(22:65) Do you not see that He has subdued to you all that is in the earth and that He has subjected the boat to the law that she floats over the sea at His bidding, and He is supporting the sky in a way that it cannot fall down without His permission ? *113 The fact of the matter is that Allah is very Kind and Merciful to the people.
*113) Here "the sky" implies the whole of the universe above and below the earth where everything is held in its own place and sphere.
