COMMENTARY on 85:1
A. Yusuf Ali:

Translation:
By the sky, (displaying) 6051 the Zodiacal Signs; 6052
Commentary:

6051  Here is an appeal to three symbols in verses 1 -3, and the substantive proposition is in verses 4-8, a denunciation of wicked persecutors of the votaries of Allah, persecutors who burnt righteous men for their Faith. The three Symbols are: (1) the Glorious Sky, with the broad belt of the Constellations marking the twelve Signs of the Zodiac; (2) the Day of Judgement, when all evil will be punished; and (3) certain Persons that will be witnesses, and certain Persons or things that will be t he subjects of the witness. See the notes following.

6052  See n. 1950 to 15:16. The Stars of the Zodiac as well as of other Constellations are like the eyes of the Night. It may be that crimes are committed in the darkness of night (literally or metaphorically). But countless eyes (metaphorically) are watching all the time, and every author of evil will be brought to book.
