«مُنْتَسِبًا إِلَى الْقَيْنِ، نَقِيًّا مِنَ الدَّرَنِ وَالشَّيْنِ»
Descended, as it were, from the smith, and free of dirt or defect.
Al-qayn denotes a smith. The speaker turns the needle’s manufacture into a family lineage. Daran and shayn pair physical soiling with blemish, reinforcing its former good condition.
