Rizq: Your allotted share of provision
Rizq is the portion set aside for you. Most worry about tomorrow rests on a hunch that the supply depends on how tightly a person holds what they already have. Seeing the day's food and money as handed over, rather than won by force, loosens the grip without stopping the work.
If you trusted God as He deserves, He would feed you as He feeds the birds, who go out hungry and come back full: trust still goes out to look
The saying comes from the Prophet. People often hear about trust and picture someone waiting at home for food to arrive at the door. Birds spend the entire morning searching, so the effort is heavy, and still nothing gets kept back in reserve.
Tadbīr: Managing and arranging your own affairs
Tadbīr is your own planning, run at full tilt. Ibn Ata Allah described the rest a person feels when they stop handling what has already been handled for them. Someone lying awake running next month's numbers is doing a job that was never theirs alone, and putting it down gives the night back.
Ibn al-waqt: The child of the present moment
Sufis call a person who lives inside the current hour a child of the moment. The mind runs ahead by habit and tries to carry next week's needs on today's strength, which nobody has. Held to the day in front of them, most people find the day is manageable, and tomorrow's strength shows up tomorrow.
Ibtilā': Testing that brings out what is inside
Ibtilā' is the testing God puts a person through. The trial does not inform God, it shows the person what they are made of. Living on just enough for the day brings out whether the trust was steady or only words, and nobody learns that while everything is secured.
