﴿ إِذْ نَادَىٰهُ رَبُّهُۥ بِٱلْوَادِ ٱلْمُقَدَّسِ طُوًى ﴾

“Lo! His Sustainer called out to him in the twice-hallowed valley:”

(How his Lord called him in the holy vale of Tuwa) the name of the valley; it was called so because it was traversed by so many prophets; it is also said: tread (Ta'), O Moses, with your feet on this valley because of its goodness and grace.
