Is it true that all grace in guiding a person belongs to Allah, and if so, what is the benefit of the choice mentioned in the Qur’an? And is it permissible for the oppressor to argue that Allah did not bestow His grace of guidance upon him?

All favor belongs to Allah Almighty in guidance, purifying souls, granting success in good deeds, and providing for people's livelihoods in this world. Allah Almighty says: "And if not for the favor of Allah upon you and His mercy, not one of you would have been pure ever, but Allah purifies whom He wills." The deficiency, flaw, and imperfection stem from the servant's own earning, even though all of it is by Allah's decree and destiny. Allah Almighty says: "Whatever good befalls you is from Allah, and whatever ill befalls you is from yourself." The servant's choice does not occur except by Allah's decree, destiny, and will. Thus, the servant does not possess the ability to guide himself independently except by Allah Almighty's divine enablement. The argumentation of the people of Hell with predestination will not benefit them, nor do they have any proof in it.
