Surah An-Naml 27:10

وَأَلْقِ عَصَاكَ ۚ فَلَمَّا رَءَاهَا تَهْتَزُّ كَأَنَّهَا جَآنٌّ وَلَّىٰ مُدْبِرًا وَلَمْ يُعَقِّبْ ۚ يَـٰمُوسَىٰ لَا تَخَفْ إِنِّى لَا يَخَافُ لَدَىَّ ٱلْمُرْسَلُونَ

And [he was told], "Throw down your staff." But when he saw it writhing as if it were a snake, he turned in flight and did not return. [Allāh said], "O Moses, fear not. Indeed, in My presence the messengers do not fear.
