Indeed, you are in the sacred valley of Tuwa. 20.13 - And I have chosen you, so listen to what is revealed. 20.14 - Indeed, I am Allah, there is no god except I, so worship Me and establish prayer for My remembrance. 20.15 - Indeed, the hour is coming, I almost conceal it, so that every soul is rewarded according to that for which it strives. 20.16 - So do not be hindered from it by one who disbelieves in it and follows his desire, for then you would perish. 20.17 - And what is that in your right hand, O Musa? 20.18 - He said: This is my staff: I lean upon it, and I bring down with it leaves for my sheep; and for me therein are other uses. 20.19 - He (Allah) said: Throw it down, O Musa. 20.20 - So he threw it down; and at once, it was a walking serpent.
