Istiʿdād: the capacity a thing is already fitted to receive
Ibn Arabi's word for how much any one thing can take in. Someone who sizes up their faith, or the small group around them, by what shows today will always come out short. Capacity and size are separate questions, and something slight can be built to hold far more than it holds right now.
A believer's intention counts for more than their action: worth is not measured by size
A saying the tradition repeats, and al-Ghazali dwells on it at length. When a contribution is obviously tiny, a person begins to feel it does not count, and quietly stops bothering. The weight sits in what the heart put in, so an unimpressive act can carry everything someone had to give.
Ṣabr: patience that stays put
Staying with something through the stretch where nothing seems to move. Between a small start and a large outcome sits a long period with nothing to show, and slowness starts to read as failure. Patience keeps a person at the work through those years, without needing proof each month that it is going somewhere.
Barakah: the increase God puts into a small thing
The old word for good that expands beyond what went into it. A person doing the arithmetic on their own effort can see it will never stretch that far, and the honest conclusion is discouraging. Growth of that kind arrives from outside anyone's private supply, which lifts the weight of the outcome off their shoulders.
Futuwwa: open-handed generosity that puts others first
The old Sufi code of hospitality and self-forgetting. Growth that stops at the person who grew is only a larger version of the same self-interest, and the tradition has little patience for that. The end of all this is a life other people can settle into, so becoming bigger means having more room for them.
