What is the interpretation of most corrupt individuals enjoying wealth and luxury, while religious people live lives of poverty or in the middle class? And how does Allah grant victory to a group that commits evil deeds and openly disobeys Him?

The believer competes only for Allah's pleasure, envies none but those who are more pleasing to Allah than themselves, and grieves only over what they have missed of that. They view the world as weighing no more than a gnat's wing in the sight of Allah, and that it is mere amusement and play, and that the Abode of the Hereafter is the true life. People are not distinguished in the sight of Allah by worldly possessions; acquiring them does not indicate His pleasure, nor does being deprived of them indicate His displeasure. Rather, it is a test. Allah the Almighty says: "As for man, when his Lord tries him and honors him and bestows favors upon him, he says: 'My Lord has honored me.' But when He tries him and restricts his provision for him, he says: 'My Lord has humiliated me.' Nay!" (Al-Fajr: 15-17). One must differentiate between gradual enticement (istidraj) and honor. The believer is tested for purification and elevation of their rank, while giving respite to the disobedient and increasing blessings upon them despite their sins is a gradual enticement for them. Allah the Almighty says: "Do they think that by Our extending to them wealth and children, We hasten to them with good things? Nay, they perceive not." (Al-Mu'minun: 55-56). Absolute justice is not established in this world, but in the Hereafter. Allah the Almighty says: "And We shall set up the scales of justice for the Day of Resurrection, so no soul will be wronged in the least. And if there is [an evil deed] even to the weight of a mustard seed, We will bring it forth. And sufficient are We as reckoners." (Al-Anbiya': 47).
