Ali 'Imran 175

إِنَّمَا ذَٰلِكُمُ ٱلشَّيْطَـٰنُ يُخَوِّفُ أَوْلِيَآءَهُۥ فَلَا تَخَافُوهُمْ وَخَافُونِ إِن كُنتُم مُّؤْمِنِينَ

innamā dhālikumu l-shayṭānu yukhawwifu awliyāahu falā takhāfūhum wakhāfūni in kuntum mu'minīna

That is only Satan who frightens [you] of his supporters. So fear them not, but fear Me, if you are [indeed] believers.
