What is the scriptural evidence for Allah Almighty’s justice, and that what He takes from a servant is by His wisdom and not oppression, and what are the implications of this belief, and how can a Muslim repel this feeling from himself?

Allah the Almighty is far removed from injustice; it is impossible for Him due to His perfect justice, as stated in the Holy Quran and the Hadith Qudsi. His actions revolve between grace, justice, wisdom, and mercy. Whatever good befalls His servants is due to His grace, and whatever affliction befalls them is due to His justice and wisdom, and is a consequence of what their hands have earned. The self is the origin of every evil that befalls a person. One must believe in Allah's perfection and His transcendence above imperfection, and that any evil that befalls him is due to his sins, not injustice from Allah.
