﴿ وَأَنْ أَلْقِ عَصَاكَ ۖ فَلَمَّا رَءَاهَا تَهْتَزُّ كَأَنَّهَا جَآنٌّۭ وَلَّىٰ مُدْبِرًۭا وَلَمْ يُعَقِّبْ ۚ يَٰمُوسَىٰٓ أَقْبِلْ وَلَا تَخَفْ ۖ إِنَّكَ مِنَ ٱلْءَامِنِينَ ﴾

“And [then He said]: “Throw down thy staff!” But as soon as [Moses] saw it move rapidly, as if it were a snake, he drew back [in terror], and did not [dare to] return. [And God spoke to him again:] “O Moses! Draw near, and have no fear - for, behold, thou art of those who are secure [in this world and in the next]!”

And ‘Throw down your staff’ and he threw it down. And when he saw it quivering moving as if it were a serpent jānn is a small snake so called because of the speed of its movement he turned his back to flee from it and did not look back in other words he did not return and so there called out the voice ‘O Moses! Come forward and do not be afraid. Indeed you are safe.
