Core meaning
To close the hand on what one holds: to seize, to withhold, or to draw back to oneself what was spread out.
Uses
قَبَضَ, يَقْبِضُ → "to tighten", "to close", "to draw back" : to close upon oneself what was opening: the provision God tightens, the miser's hand, the shadow God draws back.
قَبْضَة → "a handful", "His grasp" : what the closed hand holds: a handful of earth, or the whole earth in the hand of God.
مَقْبُوضَة, يَقْبِضْنَ → "taken", "folding" : the participle names the pledge handed over; the verb names the wings the bird draws in.
Evidence from the text
The verb goes with its opposite or with an extent: God "tightens and extends" (2:245); the birds above men align their wings, then fold them (67:19); the shadow, of which the sun is the indicator, is drawn back to Him (25:46). قبض is the movement that draws back to oneself what was open.
The same gesture names possession: the pledge is taken (2:283), that is, handed over; the Samiri takes "a handful from the track of the messenger" (20:96); and the whole earth will be "in His grasp on the Day of Appearance" (39:67). The hypocrites "close their hands" (9:67): the shut hand, which no longer gives.
