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 Moses asked his young companion when they crossed this point, "Bring us our food; the journey has made us tired." 62 Said [the servant]: "Wouldst thou believe it? When we betook ourselves to that rock for a rest, behold, I forgot about the fish - and none but Satan made me thus forget it - and it took its way into the sea! How strange!" 63 Moses said, "That is just what we were looking for." So they went back the way they had come, 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 Moosa said to him, “May I stay with you upon the condition that you will teach me the righteousness that you have been taught?” 66 [The other] answered: "Behold, thou wilt never be able to have patience with me 67 "How can you remain patient with that which you do not fully understand?" 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
