Quran 3:175 from Surah Aal-i-Imraan on Divine Marvels.
إِنَّمَا ذَٰلِكُمُ ٱلشَّيۡطَٰنُ يُخَوِّفُ أَوۡلِيَآءَهُۥ فَلَا تَخَافُوهُمۡ وَخَافُونِ إِن كُنتُم مُّؤۡمِنِينَ
English translation: (It is) only that the Shaitaan frightens (you) (of) his allies So (do) not fear them but fear Me if you are believers
Transliteration: innama dhalikumu al-shaytanu yukhawwifu awliyaahu fala takhafuhum wakhafuni in kuntum mu'minina
