(Consider) when Moses said to his young companion, "I shall continue travelling until I reach the junction of the two seas or have travelled for many years". 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 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 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 Moses said: "But that is exactly what we were seeking." So they retraced their steps. 64 and found one of Our worshipers to whom We had given from Our Mercy, and to whom We had taught knowledge of Ours. 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 said, "Indeed, with me you will never be able to have patience. 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 (Khidr) said: "Then, if you follow me, ask me not about anything till I myself mention it to you." 70
