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 between them, they forgot their fish, and it took its course into the sea, slipping away. 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: Didst thou see, when we took refuge on the rock, and I forgot the fish - and none but Satan caused me to forget to mention it - it took its way into the waters by a marvel. 63 [Moses] exclaimed: "That [was the place] which we were seeking! And the two turned back, retracing their footsetps, 64 and found one of Our worshipers to whom We had given from Our Mercy, and to whom We had taught knowledge of Ours. 65 Moses said to him: "May I attend upon you that you may instruct me in the knowledge you have been taught of the right way?" 66 He said: verily thou wilt not be able to have with me patience; 67 And how can you have patience for what you do not encompass in knowledge?" 68 He said, 'Yet thou shalt find me, if God will, patient; and I shall not rebel against thee in anything.' 69 He said: "Well, if you follow me, do not ask me concerning anything until I myself mention it to you." 70
