In the Name of God the Merciful the Compassionate.
Verily. We have adorned the world's heaven with lamps and We have made them missiles for the devils. (67:5)

Let's climb a seven-step stairway to understand this verse.

Seven steps

First step:

Just as Earth has its own inhabitants reality and wisdom require that the heavens have theirs. In Islam such beings are called angels. Despite its small size and relative insignificance. Earth is alternately filled with emptied of and replenished with living and conscious beings. Thus the heavens and their decorated palace-like constellations must have conscious and percipient beings. Just like humanity and jinn those beings observe the world. study the Book of the Universe and herald the Divine Lordship's sovereignty.

The universe's Master has embellished and ornamented it with infinite decorations beauties and inscriptions all of which require the existence of contemplative and appreciative eyes to observe and be delighted. Beauty requires a lover and food is given to the hungry. Humanity and jinn perform such a minute portion of this boundless duty glorious viewing and comprehensive worship that countless angels and spirit beings are necessary to perform these infinite and diverse duties and acts of worship.

Prophetic traditions suggest and the wisdom in the universe's order indicates that certain kinds of angels use moving bodies from planets to drops of rain to tour and view the visible material world. In addition certain kinds of animal bodies from the "green birds" of Paradise to flies serve as "aircraft" for one kind of spirits. Spirits who enter such bodies view the physical world and creation through those beings' senses. The Creator. Who continuously creates subtle life and enlightened percipient beings from dense soil and turbid water must have created many conscious beings from light even from darkness who are worthier of a higher life and spirit.
