ٱسۡتَحۡوَذَ عَلَيۡهِمُ ٱلشَّيۡطَٰنُ فَأَنسَىٰهُمۡ ذِكۡرَ ٱللَّهِۚ أُوْلَٰٓئِكَ حِزۡبُ ٱلشَّيۡطَٰنِۚ أَلَآ إِنَّ حِزۡبَ ٱلشَّيۡطَٰنِ هُمُ ٱلۡخَٰسِرُونَ ١٩
Satan has overcome them and made them forget the remembrance of Allāh. Those are the party of Satan. Unquestionably, the party of Satan - they will be the losers.
Translation: Saheeh International (English)
Each word's meaning and sound
Satan has taken control over them and through his whispers, has made them forget the remembrance of Allah, so they do not act to earn His pleasure, but only do those things that incur His wrath. They are the party of Iblīs and his followers. Know well that indeed, the party of Iblīs and his followers are the losers in the world and the afterlife, because they have sold guidance in exchange for deviance, and Paradise for the hellfire.
