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 point where the two rivers meet, they forgot their fish, and it took its way into the sea, as if through 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: lookest thou! when we betook ourselves to the rock, then I forgot the fish; and naught but the Satan made me forget to mention it, and it took its way into the sea - a marvel! 63 [Musa (Moses)] said: "That is what we have been seeking." So they went back retracing their footsteps. 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) said: "Verily thou wilt not 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 He (Moses) said: 'If Allah wills, you shall find me patient, I shall not disobey your order' 69 Said he, 'Then if thou followest me, question me not on anything until I myself introduce the mention of it to thee.' 70
