(18:62) So when they had passed beyond it, [Moses] said to his boy, "Bring us our morning meal. We have certainly suffered in this, our journey, [much] fatigue." (18:63) He said, "Did you see when we retired to the rock? Indeed, I forgot [there] the fish. And none made me forget it except Satan - that I should mention it. And it took its course into the sea amazingly". (18:64) [Moses] said, "That is what we were seeking." So they returned, following their footprints. (18:65) And they found a servant from among Our servants to whom we had given mercy from us and had taught him from Us a [certain] knowledge. (18:66) Moses said to him, "May I follow you on [the condition] that you teach me from what you have been taught of sound judgement?" (18:67) He said, "Indeed, with me you will never be able to have patience. (18:68) And how can you have patience for what you do not encompass in knowledge?"
