﴿ وَإِخْوَٰنُهُمْ يَمُدُّونَهُمْ فِى ٱلْغَىِّ ثُمَّ لَا يُقْصِرُونَ ﴾

“even though their [godless] brethren would [like to] draw them into error: and then they cannot fail [to do what is right].”

(Their brethren) the brethren of the idolaters, i.e. the devils (plunge them further) drag them further by means of their insinuations (into error) into disbelief, error and sin (and cease not) and they refrain not from it.
