When Moses said to his servant (Joshua): "I will not give up till I reach the confluence of two oceans, or I will journey on and on." 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 And when they had gone further, he said unto his servant: Bring us our breakfast. Verily we have found fatigue in this our 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 He said: This is what we sought for; so they returned retracing their footsteps. 64 Then found they one of Our slaves, unto whom We had given mercy from Us, and had taught him knowledge from Our presence. 65 Musa said to him: Shall I follow you on condition that you should teach me right knowledge of what you have been taught? 66 He replied, "You will not be able to have patience with me. 67 "And how can you have patience about a thing which you know not?" 68 Moses said, "God willing, you will find me patient, and I will not disobey you in any thing." 69 Said he, 'Then if thou followest me, question me not on anything until I myself introduce the mention of it to thee.' 70
