(And recount to them the story of Moses) when Moses said to his servant: "I will journey on until I reach the point where the two rivers meet, though I may march on for ages." 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 When they had gone past (the confluence), Moses said to his servant: "Give me my breakfast. I am exhausted from this journey." 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, 'Shall I follow thee so that thou teachest me, of what thou hast been taught, right judgment.' 66 He (Khidr) said: "Verily! You will not be able to have patience with me! 67 'For how can you bear patiently with that which you have never encompassed in your knowledge' 68 He said: Allah willing, thou shalt find me patient and I shall not in aught gainsay thee. 69 He said: "Well, if you follow me, do not ask me concerning anything until I myself mention it to you." 70
