وَمِنْ شَرِّ النَّفَّاثَاتِ فِي الْعُقَدِ
And from the evil of those who blow upon knots. (113:4)
Al-naffāthāt is a definite feminine sound plural, genitive after sharr. It describes agents by a particular action associated with blowing or whispering over knots. The phrase fī al-ʿuqad specifies the action; it does not condemn every instance of ordinary blowing.
Morphological description is not a license to project the verse indiscriminately onto an entire social category. The wording is tied to a specific harmful practice.
