Overall meaning : I swear by Mount Sinai, by the book that is inscribed on an unrolled parchment, by the House that is frequently visited by the angels in the heavens, by the sky that We have raised and made as a roof for the earth, and by the swollen sea: Your Lord’s punishment will surely descend on those who justly deserve it, and there will be none to prevent it from taking place or saving them from it.
