«ثُمَّ خَطَفَتِ الدِّرْهَمَ خَطْفَةَ الْبَاشِقِ»
She snatched the dirham as a hawk swoops upon prey.
The hawk simile captures speed and decisiveness. No actual bird is involved; the comparison transfers the bird’s sudden strike to the woman’s movement.
Placed after the bargaining, the snatch reveals how urgently the coin was desired. One vivid action replaces extended narration of motivation.
