English translation (Saheeh International)

And We have certainly beautified the nearest heaven with lamps [i.e., stars] and have made [from] them what is thrown at the devils¹ and have prepared for them the punishment of the Blaze.

Brief commentary

And verily I adorned the nearest sky to the earth with shining stars, making them shoot and repelling with them the satans with them who try to eavesdrop. I have also prepared for them a blazing fire in the afterlife.
