(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 Then, when they reached their meeting, they forgot their fish, and it took its way into the sea, burrowing. 61 And when they had gone further, he said to his assisting youth; 'Bring us our breakfast; we are worn out from 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 was what we were seeking after:" So they went back on their footsteps, following (the path 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 Moses said to him, "May I follow you, so that you may guide me by what you have been taught?" 66 [The other] answered: "Behold, thou wilt never be able to have patience with me 67 for how couldst thou be patient about something that thou canst not comprehend within the compass of [thy] experience?" 68 Replied [Moses]: "Thou wilt find me patient, if God so wills; and I shall not disobey thee in anything!" 69 He said: If you would follow me, then do not question me about any thing until I myself speak to you about it 70
