Surah 26. Ash-Shuara

27Thub 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.

28Some commentators under the influence of the Israelite traditions have translated baida' as white and have taken it to mean that the healthy hand when drawn out of the armpit became white as if struck by leprosy. But commentators like Ibn Jarir, Ibn Kathir, Zamakhshari, Razi, Abul Sa'ud `Imadi, Alusi and others are agreed that baida' here means shining and bright. As soon as Prophet Moses took out his hand from the armpit, it made the whole place bright as if by the sun. For further explanation, see E.N. 13 of Ta Ha.
