Sahih Bukhari Volume 4, Book 54, Hadith Number 498.

Narated By Ubai bin Kab : That he heard Allah’s Apostle saying, “(The prophet) Moses said to his attendant, “Bring us our early meal’ (18.62). The latter said, ‘Did you remember when we betook ourselves to the rock? I indeed forgot the fish and none but Satan made me forget to remember it.” (18.63) Moses did not feel tired till he had crossed the place which Allah ordered him to go to.”
