Quran 34:20 from Surah Saba on Divine Marvels.
وَلَقَدۡ صَدَّقَ عَلَيۡهِمۡ إِبۡلِيسُ ظَنَّهُۥ فَٱتَّبَعُوهُ إِلَّا فَرِيقٗا مِّنَ ٱلۡمُؤۡمِنِينَ
English translation: And certainly found true about them Iblis his assumption so they followed him except a group of the believers
Transliteration: walaqad saddaqa alayhim ib'lisu zannahu fa-ittaba'uhu illa fariqan mina al-mu'minina
