7:202
وَإِخْوَٰنُهُمْ يَمُدُّونَهُمْ فِى ٱلْغَىِّ ثُمَّ لَا يُقْصِرُونَ
wa-ikh'wānuhum yamuddūnahum fī l-ghayi thumma lā yuq'ṣirūna
the followers of devils are led relentlessly into error by them and cannot stop.
But (as for) their brothers (the devils) they (i.e. the devils) plunge them deeper into error, and they never stop short.
