That is only Satan who frightens [you] of his supporters. So fear them not, but fear Me, if you are [indeed] believers.
The Saheeh International Quran Translation
إِنَّمَا ذَٰلِكُمُ ٱلشَّيْطَٰنُ يُخَوِّفُ أَوْلِيَآءَهُۥ فَلَا تَخَافُوهُمْ وَخَافُونِ إِن كُنتُم مُّؤْمِنِينَThat is only Satan who frightens [you] of his supporters. So fear them not, but fear Me, if you are [indeed] believers.
