This Is My Faith - Al-fatlawi, Ali - الصفحة ٨٤ - Introduction to Divine Justice
Consequently, He cannot be unjust nor do repulsive acts.
Anwar: Well said! But I still have questions if you don’t mind.
Hasan: Of course, ask whatever you want.
Anwar: You said, ‘justice is to give everyone their due’; does that mean that we are entitled to claim certain rights from the Most Exalted Allah?
Hassan: This is an excellent scientific question, and I am pleased that you asked. The reward for the good deeds is no one's due; this is out of His mercy, because we are His creatures as we are not entitled to claim anything. However, the Glorious Allah, out of mercy and kindness, gave us this right to be in charge of our deeds and considered certain rewards for that as He put it in these Verses:
(Say: Unto whom belongeth whatsoever is in the heavens and the earth? Say: Unto Allah. He hath prescribed for Himself mercy…)٦;١٢.
(Your Lord hath prescribed for Himself…)٦;٥٤.
