Waqt: The present moment, the one place a person can act
Waqt names the moment you are standing in. Some chances stay open for a short while and then close, and whatever was given inside that window is all that counts. Effort held back for later cannot be carried back, because the moment it belonged to has already gone.
Adab: Courtesy, how a student acts toward a guide
Adab covers the care a person takes with someone further along than they are. Doing the smallest acceptable amount is itself an answer, and it says the instruction was not fully trusted. Someone who holds back that way keeps a hand on the wheel, and the help only reaches as far as the opening left for it.
Himma: Aspiration, how far a person's wanting reaches
Himma is the reach of what someone wants, and Ibn Arabi treats it as the strongest force in a person. Aiming low can feel like modesty or good sense, when it comes from not believing much was on offer. Where the wanting stops, the effort stops with it, and afterward the small result looks like circumstance rather than choice.
Ṣidq: Truthfulness, wanting a thing all the way through
Ṣidq means the inside of a person matches what they claim to want. Someone can go through the motions of asking for a large thing while quietly settling for a small one, and half-hearted effort is where the settling shows. Wanting something fully looks like spending everything you have on it, before you know whether it will work.
I am as my servant expects me to be: expectation sets the size of what arrives
The Prophet passed this on as words from God. A low expectation quietly caps what a person will even attempt, so the outcome matches the guess and then seems to prove the guess right. Someone who expects a generous answer puts in a generous effort, and that effort is what the answer has to work with.
