Divine justice in the Koran's view

In many of the verses of the Holy Koran it is highly mentioned that Divine justice exists thought the universe as well as on the Day of Judgement:

1- God testifies there is no deity except – Himself, and so do the angels and persons possessing knowledge. Maintaining fairplay, there is no deity except him.( 3:18)

The term “deity” in this verse refers to God justice.

2- we have sent  our messengers  with explanation, and sent the Book and Balance down along with them , so  that – mankind may conduct themselves will all fairness .( 57:25)

Sending the prophet as well as the miracles with them to human indicates Divine justice.

3- While He has raised the sky up and placed scales [there] (55:7)

Creation of the universe indicates that God is just.

4-say: “My Lord has ordered me to play fair.( 7:29)

5- He said: “My pledge does not apply to evildoers.(2:124)

This verse confirms that   according to Divine justice prophecy as a divine pledge is grouted to the persons doing honorable deeds, intending everyone is not permitted to be a prophet or on Imam.
