According to my belief, justice and worshiping God are very much connected: Say, my lord has enjoined justice. And fix your attention aright at every mosque, and call upon Him, making yourselves sincere towards Him in religion. As He brought you into being, so shall you return. ( Quran 7:30)
The believer who go to mosque are expected to honor dues of God.
Ahmadiyya Caliph mentions the following verse to explain the original point of justice and worship: Verily, Allah enjoins justice, and the doing of good to others; and giving like kindred; and forbids indecency, manifest evil, and wrongful transgression. He admonishes you that you may take heed. (Quran 16:91)
Hence, justice is connected with worship through being nice with fellow human beings.
Sadly, the Christian bible also says that the Quran is a work of mere fiction.
Uh the bible was written some 400-500 years before the Koran was written down by Mohamed so how does that work?
