quran:20:20 –

So he threw it down, and thereupon it was a snake, moving swiftly.  

And he cast it down, and lo! it was a serpent, a giant snake, moving swiftly, moving about on its belly swiftly with the speed of a small snake — which is called al-jānn and which is ˹also˺ used to refer to this ˹serpent˺ in another verse ˹Q. 27:10; Q. 28:31˺.
القرآن:٢٠:٢٠ –

فَأَلْقَاهَا فَإِذَا هِيَ حَيَّةٌ تَسْعَىٰ  

{فألقاها فإذا هي حية} ثعبان عظيم {تسعى} تمشي على بطنها سريعا كسرعة الثعبان الصغير المسمى بالجان المعبر به فيها في آية أخرى.
