Overall meaning : Blessed is Allah in whose hand all dominion rests and who has power over all things. It is He who has created death and life so that He may test you, people, and prove those of you who, according to His foreknowledge, are best in deeds. He is the All-Mighty, the All-Forgiving.
It is He who has created seven heavens, one above the other. You will never see any flaws or imperfections whatsoever in the creation of the heavens which the All-Compassionate God has so perfectly created. Look up towards the sky: can you detect a single flaw? Then look again and again: your sight will in the end return to you utterly frustrated and fatigued, having perceived no incongruity whatsoever!
We have adorned the lowest heaven nearest to the earth with shining stars, and made them as missiles with which to pelt the devils that attempt to eavesdrop on the highest assembly of the angels; and We have prepared for them the punishment of the intensely burning Fire in the life to come.
