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 Moses asked his young companion when they crossed this point, "Bring us our food; the journey has made us tired." 62 The servant said: "Did you see what happened? When we betook ourselves to the rock to take rest, I forgot the fish - and it is only Satan who caused me to forget to mention it to you - so that it made its way into the sea in a strange manner." 63 Musa said: that is that which we have been seeking. So they turned back upon their footsteps, retracing. 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 attend upon you that you may instruct me in the knowledge you have been taught of the right way?" 66 He replied, "You will not be able to bear with me patiently. 67 for how couldst thou be patient about something that thou canst not comprehend within the compass of [thy] experience?" 68 [Moses] said, "You will find me, if Allah wills, patient, and I will not disobey you in [any] order." 69 He said, "Well then, if you would follow me, do not ask me about anything till I speak of it to you." 70
