(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 point where the two rivers meet, they forgot their fish, and it took its way into the sea, as if through a tunnel. 61 Moses asked his young companion when they crossed this point, "Bring us our food; the journey has made us tired." 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, "That is exactly what we are seeking. They followed their own foot prints back (to the rock)." 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 on [the condition] that you teach me from what you have been taught of sound judgement?" 66 (The other) said: "Verily thou wilt not be able to have patience with me!" 67 And how can you have patience for what you do not encompass in knowledge?" 68 Moses said, "God willing, you will find me patient, and I will not disobey you in any thing." 69 He said: If you would follow me, then do not question me about any thing until I myself speak to you about it 70
