«رَشِيقَةَ الْقَدِّ، أَسِيلَةَ الْحَدِّ»
Graceful in form, smooth and fine at the edge.
Rashīqat al-qadd praises graceful form; asīlat al-ḥadd introduces the smoothness of a sharp edge. Human-sounding attributes personify an implement, obscuring its identity while hinting at its physical structure.
The reader must combine two classes of clue—humanized description and the vocabulary of an edge. One phrase by itself cannot settle whether the dispute concerns a person or an object.
Personification makes the implement sound human; the disputed object remains a needle.
