بِرَبِّ النَّاسِ مَلِكِ النَّاسِ إِلَٰهِ النَّاسِ
In the Lord, Sovereign and God of humankind. (114:1–3)
Al-nās is repeated in all three genitive constructions. A pronoun could have reduced the wording, but renewed explicit mention sustains the human referent and the emphasis of the appeal. This is relevant to explicit naming where a pronoun might be possible and purposeful repetition.
It does not mean that the first three verses enumerate three different evils. One human community is related to three descriptions of the one sought for refuge.
Across the surah al-nās appears 5 times: in verses 1–3 with divine descriptions, in verse 5 as the people affected, and in verse 6 within the expression concerning possible sources of whispering. Repetition accompanies a changing syntactic relationship.
