مِنْ شَرِّ مَا خَلَقَ
From the evil of what He has created. (113:2)
مِنْ شَرِّ الْوَسْوَاسِ الْخَنَّاسِ
From the evil of the retreating whisperer. (114:4)
Al-Falaq begins with broadly phrased harm and then specifies several dangers. Al-Nās first develops three divine descriptions, then names a particular threat, clarifies its activity and concludes with possible sources. Both progress by elaboration, but their rhetorical architectures differ.
It would therefore be inaccurate to label every step in both surahs as the same instance of “particular after general.”
