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 So when they had reached the junction of the two (rivers) they forgot their fish, and it took its way into the sea, going away. 61 But when they had gone farther, he said to his servant: Bring to us our morning meal, certainly we have met with fatigue from this our journey. 62 He replied: 'What do you think, I forgot the fish when we were resting on the rock. None but satan made me forget to mention this; it made its way into the sea in a marvelous fashion' 63 Moses said: "But that is exactly what we were seeking." So they retraced their steps. 64 So they found one of Our servants, on whom We had bestowed Mercy from Ourselves and whom We had taught knowledge from Our own Presence. 65 Moses said to him, "May I follow you, so that you may guide me by what you have been taught?" 66 He said: Lo! thou canst not bear with me. 67 "How can you remain patient with that which you do not fully understand?" 68 Moses said: "Thou wilt find me, if Allah so will, (truly) patient: nor shall I disobey thee in aught." 69 He said, “Therefore if you stay with me, do not ask me about anything until I myself mention it to you.” 70
