(At-twur) 52 : 6
وَالْبَحْرِ الْمَسْجُورِ
And the sea which will be kindled with fire.
It is told in verse 81: 6 that as part of Doomsday, the sea will be set ablaze. The structure of water is a molecule containing two hydrogen atoms and one oxygen atom. Due to the severe vibration and thereby the severe blasting of Doomsday, the elements of water, hydrogen, and oxygen will be separated; and hydrogen, which is a combustible element, will be ignited with the help of oxygen, which helps to ignite.
