Waqt: The present hour
The Sufis call a person the child of the moment, given only the hour in front of them. Someone weighing which effort will pay off is living in a time that has not arrived, and the hours slide by unused. Attention comes back to the work this hour allows, so the day gets spent on doing rather than on calculating.
Ghayb: The unseen
The Quran holds that the keys of the unseen belong to God alone, and how a thing will turn out sits behind that door. Wanting to know in advance which effort takes is asking for a key nobody has. When a person stops waiting on that certainty, the pressure to guess correctly drops, and plain work becomes possible again.
Tawakkul: Trust in God
al-Ghazali is blunt that trusting God never means dropping the work; his example is the farmer who still plants. The heart rests on God while the hands keep doing what hands can do. Someone holding both is not staking everything on one result, so work that fails does not feel like proof they were foolish. Effort stays steady because it no longer rests on a forecast.
Ikhlāṣ: Sincerity
Sincerity places the aim of an action in God alone. When visible payoff is the only thing that counts, work with no measurable return feels pointless to start, and people hold back and hedge. With the aim set elsewhere, an effort keeps its worth even when nothing shows for it, and the next one still gets done.
Riḍā: Contentment with what God gives
Riḍā means being at peace with how things land. Someone who measures the result against the one they wanted stays sore about it long after the work is over. Contentment takes whatever arrived as what God gave, including the times when more than one effort does well. The comparing stops, and attention is free for the next piece of work.
