Relieve yourself of the burden of running your own affairs: the quarrel starts in private planning
Ibn Ata Allah wrote that line for people worn out by managing their own lives. The fight with God usually starts small, as a private plan for how things were supposed to go, held up against what happened instead. When the plan is set down, most of the anger goes down with it.
ʿUbūdiyya: Being a servant
Ibn Arabi kept two roles strictly apart, the Lord's part and the servant's part. Trouble begins when a person quietly takes on the first, deciding what should be made of their life and by when. The relief in the second role is that the outcome was never their assignment. A person does their own work, and the shape of the whole belongs to someone else.
He is not asked about what He does: the demand for reasons gets turned around
The Quran puts this flatly, and Sufis return to it when someone is stuck demanding an explanation. Wanting an account of why life is going this way feels like fairness from the inside, but no one is owed the review. Once a person stops holding out for reasons, the demand loses its grip and the days get lighter.
Ḥusn al-ẓann bi-llāh: Thinking well of God
A saying of the Prophet has God speak directly: I am as my servant thinks of Me. Under most arguing with God sits a suspicion that the work is being done badly, and that suspicion colors everything after it. Every hard turn then reads as proof, until thinking well of God changes how the same day looks from the inside.
Riḍā: Contentment with what you are given
Al-Ghazali describes riḍā as the settled place past patience, where a person stops wishing the day had gone another way. Gritting your teeth is still arguing, only quietly, and keeping that up takes most of someone's strength. Contentment arrives when the wish for a different life loses its pull, and the life a person has stops feeling like a mistake.
