Tafseer Abu-al-A'la Maududi

Page 368 English Traditional

*27) Thub an means a serpent. At other places, the Qur'an has used hayyatun (snake) and jaann (a small snake) to describe the snake of the staff. The interpretation given by Imam Razi is that the snake of the staff looked like a serpent from its big size and has been called jaann on account of its swift movement which is characteristic of small snakes.
