Adl (Justice of God)
It means that God is Just. He is not a tyrant. Everybody's reward will depend upon his or her own deeds. He who obeys His commands will be awarded a place in Paradise and he who disobeys Him will be sent to Hell. In this regard, the Qur’an says:
(3:18) “ALLAH affirms that there is no god but He: and so do the angels, and these endowed with knowledge, He is standing firm in justice”.
(2:82) "And those who believe and do righteous good deeds, they are dwellers of paradise, they will dwell therein forever."
(99:7) "So, whoever does an atom's weight of good shall see it;"
(99:8) "and whoever does an atom's weight of evil shall see it."
