And (remember) when Musa (Moses) said to his boy-servant: "I will not give up (travelling) until I reach the junction of the two seas or (until) I spend years and years in travelling." 60 But when they reached the Junction, they forgot (about) their Fish, which took its course through the sea (straight) as in a tunnel. 61 When they had gone past (the confluence), Moses said to his servant: "Give me my breakfast. I am exhausted from this journey." 62 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". 63 Moses said, "That is just what we were looking for." So they went back the way they had come, 64 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. 65 Musa said unto him: shall I follow thee that thou mayest teach me of that which thou hast been taught a directive knowledge. 66 He (Khidr) said: "Verily! You will not be able to have patience with me! 67 "How can you remain patient with that which you do not fully understand?" 68 Moses replied: "You shall find me, if Allah wills, patient; and I shall not disobey you in anything." 69 Said he, 'Then if thou followest me, question me not on anything until I myself introduce the mention of it to thee.' 70
