Surah Saba, Verse 20

وَلَقَدۡ صَدَّقَ عَلَيۡهِمۡ إِبۡلِيسُ ظَنَّهُۥ فَٱتَّبَعُوهُ إِلَّا فَرِيقٗا مِّنَ ٱلۡمُؤۡمِنِينَ٢٠

walaqad ṣaddaqa ʿalayhim ib'līsu ẓannahu fa-ittabaʿūhu illā farīqan mina l-mu'minīna

And Iblees had already confirmed through them his assumption, so they followed him, except for a party of believers.
