(Consider) when Moses said to his young companion, "I shall continue travelling until I reach the junction of the two seas or have travelled for many years". 60 But when they reached the junction of the two seas, they forgot their fish, and it took its way through the sea as in a tunnel. 61 And after the two had walked some distance, [Moses] said to his servant: "Bring us our mid-day meal; we have indeed suffered hardship on this [day of] our journey!" 62 He said, 'What thinkest thou? When we took refuge in the rock, then I forgot the fish-and it was Satan himself that made me forget it so that I should not remember it -- and so it took its way into the sea in a manner marvellous.' 63 Moses said: "That is what we were looking for." So the two turned back, retracing their footsteps, 64 Then the twain found a bondman from Our bondmen, him We had vouchsafed a mercy from before Us, and him We had taught from Our presence a knowledge. 65 Moses said to him, "May I follow you, so that you may guide me by what you have been taught?" 66 He said: Lo! thou canst not bear with me. 67 "How can you bear that which is beyond your comprehension?" 68 He (Moses) said: 'If Allah wills, you shall find me patient, I shall not disobey your order' 69 Said [the sage]: "Well, then, if thou art to follow me, do not question me about aught [that I may do] until I myself give thee an account thereof." 70
