Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)!
[Qur'an 7:107]

(2) the Radiant Hand:

And he drew out his hand, and behold! it was white to all beholders!

We punished the people of Pharaoh with years (of droughts) and shortness of crops; that they might receive admonition.

So We sent (plagues) on them: Wholesale death, Locusts, Lice, Frogs, And Blood: Signs openly self-explained: but they were steeped in arrogance,- a people given to sin.
[Qur'an 7:133]
