وَذَكِّرْ فَإِنَّ ٱلذِّكْرَىٰ تَنفَعُ ٱلْمُؤْمِنِينَ
Wa zakkir fa innaz zikraa tanfa'ul mu'mineen
Öğüt ver; doğrusu öğüt inananlara fayda verir.
And remind, for the reminder benefits those who believe.
Placed right after the instruction to turn away, this line keeps the work going: the Prophet is released from responsibility for the outcome and told to continue anyway. Dhikrā means calling something back to mind rather than teaching it for the first time, which assumes the hearer already knows and has let it slip. That is why the benefit is named for believers — the people most likely to think they have heard it already.
