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 junction of the two seas, they forgot their fish, and it took its way through the sea as in a tunnel. 61 Moses asked his young companion when they crossed this point, "Bring us our food; the journey has made us tired." 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 Moses said: "That was what we were seeking after:" So they went back on their footsteps, following (the path they had come). 64 and there they found one of Our servants upon whom We had bestowed Our mercy, and to whom We had imparted a special knowledge from Ourselves. 65 Moses said to him: 'May I follow you so that you can teach me of that you have learned of righteousness' 66 He answered: "You will surely not be able to bear with me. 67 "And how canst thou have patience about things about which thy understanding is not complete?" 68 He said: Allah willing, thou shalt find me patient and I shall not in aught gainsay thee. 69 He said, "Well then, if you would follow me, do not ask me about anything till I speak of it to you." 70
